Cpu Cores

[ransom]

Hardware:Q6600(4Cores)
1)when i run windows 2003 with "4 Cpu Sockets",I can see 4 cpus are running on Windows 2003.
2)When I run windows xp pro(SP3) with "4 Cpu Sockets",I only see 2 cpus are running on Windows xp,and the system is very slower than Windows 2003,why?how can I make windows xp running 4 Cpu cores?

WinXP Pro only supports 2 sockets - licensing limitation from Microsoft.

So you should configure 1 socket and 4 cores. or 2 sockets and 2 cores. does not make any difference on the KVM side.

Note: the sockets/core is only working in the 2.6.24 and 2.6.32 kernel branch, not in 2.6.18

Hello Tom,

I trie the two ways:
1)cpu sockets=1 cores/socket=4
2)cpu sockets=2 cores/socket=2

shutdown and windows and start the windows,but I still see windows xp only have 2 cores,the system is slower than windows 2003(running on 4 cores).

I only run one kvm in this server(Windows xp or Windows 2003),but seems windows xp(Only running 2 cores) is very slower than Windows 2003(running 4 cores),so I should try let Windows xp running on 4 cores.Do you have any idea?

yes, you run an old system, update to the latest 2.6.24, see http://pve.proxmox.com/wiki/Downloads

Hi,
like Tom wrote: you have an old system (pve 1.4).
apt-get dist-upgrade ?

you are running a mixture of packages, correct it!

for explanation, take a look here: http://pve.proxmox.com/wiki/Proxmox_VE_Kernel

you are running kernel 2.6.24-8 and you are using the pve-qemu-kvm from 2.6.18 - this will never work.

solution for a clean 2.6.24 system:

aptitude install proxmox-ve-2.6.24

pveversion -v should give you the following (after reboot):

pveversion -v

pve-manager: 1.5-8 (pve-manager/1.5/4674)
running kernel: 2.6.24-10-pve
