processors

[RaNa]

hey guys i had my windows xp on a dual core proxmox server and now i movies it to a quad core proxmox server in the windows task manger i see a dual care but in my device manager i see 4 processors



i was playing with in proxmox Cores/Socket: CPU/Socket: and got 4 cores to show up but and i open the task manger and run a program it looks like its only using one core ummm

if you configure 1 socket, 4 cores you should see 4 cpu´s in the task manager. do you use winxp home or prof?

post your:

• pveversion -v
• cat /etc/qemu-server/VMID.conf of your winxp

...XPHome edition for example is limited to 1 socket and 2 cores, is it not? Which version are you using?

...there are not that many programs that can make use of more that a single core at a time.
Some video transcoding programs or other number-crunching applications can actually do....so I suspect this is totally normal.
Which program did you use?

XP Home is limited to 1 socket, but if it is patched with most recent updates, I'm pretty sure it will still be able to see up to 4 cores.

You also have some view options on what & how it will show things to you.

i got 4 cores to show up but the problem now is that its only using one core and how do i know this in the windows task manger i can see one of the cares being used 100% and 3 cores at like 0% maybe 1% and that makes it really slow sense its only using one care

What it it doing/running right now? Unless it is working, you probably won't get it to use most of its resources, because the system will just 'idle' along with most of the system processes only using one core.

Can you start a CPU resource hog, and check it again? Try starting 2 of them, just in case they are only single-threaded, and see if that gets spread around, or if both of them only run on one CPU. If they seem to stick to one cpu, try going to the process list, and see if you can assign one of them to a different core? (That feature may not be available in XP Home, but if it is, it would be labeled something like "Set Affinity")

ps. Which processes are using the 100% in the one core now?
