virtual lamp
I'm an apprentice electrician first year and that you have installed recently Multisim v11. I can't find information in the help files to answer these questions and hope for more help. Why a filament is sometimes Red? Why the lights sometimes flash?
Thank you
Greg
Greg,
Multimeters of wire in each of the 3 lights. You will see that each lamp has a different voltage through it. If you compare the voltage across the lamp with the with the nominal value of the lamp, it follows that what I mentioned earlier. Voltage too low, the lamp is off. Tension near the coast, the lamp is on, but not red. Voltage equal or superior, the lamp is on and red.
The voltage drop across each lamp is based on the setting of the voltage and the power of the lamp. Multisim seems to use of a simple Ohm's law calculation to determine the resistance of each lamp based on the voltage and power. The formula is R (ohms) = (v * v) / Watts. If you are replacing each bulb with the calculated resistance, the voltage drop will be the same.
See the attached file for the link between the tensions as well as the effect of the tension along a sine wave AC on the flickering effect.

How to change the local IP on the virtual NETWORK adapter for Web server address
Hi all
I have a physical Windows system, on which I run VMware Workstation 9. Now on VMware I run Ubuntu 12.10 a LAMP for a Web server.Problem:Now, my local IP address for my NETWORK card virtual (using the Ubuntu one) at the address 192.168.159.7 and my router only emits the 10.0.0.x range IP addresses. So if I want to port forward to the virtual NETWORK adapter that has a 192.168 address, I can't, so my LAMP Web server are not accessible to the outside because the router does not send packets on port 80 to the virtual card... How to fix this?The only way I guess that is to be assigned an ip address of 10.0.0.x to the virtual NETWORK adapter?But how do I do this?I tried to do it on the host from the Windows machine with "get my IP address automatically", but she emits an 192.168 address every time...Thank youWelcome to the community,
I guess that the virtual computer is currently configured to "NAT" or "Host-Only' networking! That would explain the 192.168.x.x IP address.
There are 2 options to be able to access the web server on the virtual computer.
1. with "NAT" network configured
In this case forward port 80 to the IP address of the host and configure the port forwarding on the virtual computer in the "Virtual Network Editor. This way you can leave the IP address on the private network of 192 (if it is currently set to NAT)
2. use "Bridged" network layout
Reconfigure the virtual NETWORK adapter to the machine virtual networking "Bridged" within the parameters of the virtual machine, assign an IP address from your router network (10.x.x.x) and do the port forwarding on the router directly to the IP address of the virtual machine.

Shared behavior of the virtual machine on the host system shutdown
Shared behavior of the virtual machine on the host system shutdown
Greetings,
I installed WIn7 - 64 bit host system, WS8 and there seems to be a very nice and high quality configuration. I am very happy.
There is a shared VM and it's a Setup 64-bit Ubuntu 10.04 Server functioning as a base configuration LAMP for some basic web applications, etc..
I was unable to find the settings to control the behavior of the VM shared with the system that hosts stop. When I stop the host system, I believe that the common VM is off tension or stop gracefully, I don't know who. What I like best is for the shared VM will not apply instead. The reason is that starting the virtual machine is a bit complicated and requires manual intervention. Whereas, if it is stopped since a State suspended without manual intervention is necessary.
I found that if there is a loss of power, I can hibernate the host system in time before my battery runs out. Resuming the host hibernate system works correctly and the VM shared within WS8 is back to its previous functional State.
It would be nice and helpful being able to stop or restart the host system and know that the shared virtual machine has been automatically suspended. So now I have to log on to the user account from the host system and open WS8 and manually suspend the virtual machine before you stop or restart the host system.
Is there a way to have the shared VM automatically suspended when the host system is stop?
Thank you for your time and attention.
You can configure the stop action by editing the following file:
%ProgramData%\VMware\hostd\vmAutoStart.XML
If you want to configure the action stop for all virtual machines, find the section of
under the section. Change it on hold If you want to change the action stop for only this one machine virtual, you must first configure this shared VM to be started automatically (in WS, right-click on the item 'VMs shared' in the library, select "manage computers virtual auto-start '). After doing this, manually change the vmAutoStart.xml. Find the entry for the virtual machine in the
section (if you have more than one computer configured to autostart virtual, it will take some more digging to understand what VM to change). Change the entry for this virtual machine to hang. Save the file. Reboot the host (not auto-start power actions are only made when the host is restarted). Now when stop you the host, WS should suspend the VM (s)
As always, manually edit the configuration files is not considered supported its use. Save the file before you edit. Adjust at your own risk.

Loss of confusion concerning the data on the virtual disk in VMWare
The evening
Excuse the amateurism, but I'm looking for help with a problem I have with a virtual machine.
I created a Virtual Machine with a virtual disk of fixed size for use as a LAMP (in this case, Ubuntu 9.10) development environment. I have used this in the course of nearly a year and have taken quarterly snapshots, or before, I did something stupid to the BONE. So far we five snapshots and a clone that I got a month ago.
Recently, I created an another VM to install the configuraiton of LIGHT even on Ubuntu 10.04 (I wanted a new installation). I didn't know it was a bad idea in time, so I created a second disk on the VM 10.04 and mounted the main drive of the virtual machine 9.04. Obviously, 10.04 altered the disc somehow, as I had received the "+ the Ramdisk parent has changed since the child was.
created. + "error every time I tried to start it.
After several unsuccessful attempts to try to find a recent clone, I created a new virtual machine and up from 9.04 virtual disk. However, from the start of this virtual machine, I went back to, what I believe to be, the first State of the virtual machine before snapshots. However, it is also possible that I lost the correct VM while trying to find a recent clone (of course, I hope it's a snapshot problem and not a problem of stupidity).
My question is, is - it possible that the disc that I mounted does not take into account my snapshots?
See http://sanbarrow.com/vmdk-errors.html#e4 for an explanation of the error and some tips how to fix it.
If in doubt ask before doing anything more that could "destroy" the disc.

VSphere number of virtual machines per CPU
I've seen estimates of virtual machines per CPU and I understand that it depends on a combination of things. I think 4-5 virtual machines per CPU is up around. We run HP Proliant DL380 G5s (2 quad core) and it seems like that 4-5 per CPU core will be our number. Memory being the main factor limiting.
I am now watching the servers (2 quad core) Proliant DL380 G6 and recital 72 GB of memory. Before I size like that, I want to know if the 8-10 mV by heart is conceivable. Even if I think that my current hardware could choke if I tried, I thought that perhaps most recent families of processor as the Proliant G6 Nehalem with VSphere improvements with regard to the planning of the CPU that could be a possibility.
Also, I assumed variess speed processor directly with the virtual machine by core equip. As CPU speed increses # or virtual machines by increases in Basic. Is this correct?
You're right it depends on many things, but for the general basic rules 4 - 6 virtual machines by heart for ESX 3.x and you can run no risk 6 to 8 virtual machines to vSphere, if you know that your virtual machines are use of the lamp, then pushing to 6-10VMs might do, but you should perhaps follow the activities and decrease if resources are hammering. vSphere certainly has better CPU planning services and get the best performance from predecessor. I test it on a test environment and the maximum stress and see how it runs. What types of workloads and servers do you think?
If you found this information useful, please consider awarding points to 'Correct' or 'useful '. Thank you!!!
Kind regards

What App would you recommend to run virtual machines on an Imac?
I would try to have virtual machines running on my IMac, but I'm having a hard time finding any material on this topic from apple.
Ideally, I would like to my main x os to start and then simply turn a small virtual machines or containers from OSX.
Any recommendations? or articles about the support of Apple for such a thing?
There are three choices:
The first two are commercial products. The third is a free, open source. Three Parallels is the best.

Kernal_task with virtual memory, slow computer
I have an iMac 21.5 inch end 2013 with 8 GB RAM on OS X 10.11.6. The computer is incredibly slow and hangs up during long periods of time (minutes). In addition, I noticed when you save to my Time Capsule (ethernet connection, wifi is turned off) it will just make a break to half way through and stay there (e.g., 789 MB 450MO) for 30-45 min. activity monitor shows kernal_task taking up huge amounts of time processor (5:02:09), son (118), slow down wake ups (2752), and when I select the process name it shows the size of real but 781,2 MB of memory the size of the virtual memory of 70,51 Go.
I don't have any external monitors, hard drives (except the time capsule), etc. connected. Any ideas of what I can do?

Dungeon of virtual keyboard to appear when you use bluetooth keyboard
I use a surface 3 pro with a keyboard bluetooth as the main method of entry. The recent Firefox update keeps popping up a virtual keyboard of the system on each input field. This is a nice feature to have while no external keyboard is connected. However, it is extremely inconvenient if you have a connected bluetooth keyboard.
Please would you consider to provide a toggle button to turn this feature off or just to test if a bluetooth keyboard is connected before appearing the virtual keyboard?
Thank you.
Hi, if you want to disable this feature, please enter about: config in the address bar of firefox (confirmed the message information where it appears) and search for the preference named ui.osk.enabled. Double-click it and change its value to false.
