Hi all,
I have just installaed PVE version 2.2 (last updated release) on a dual socket (4 cores per socket) server.
Here the detail about 1 of che 8 CPU:
processor : 0
vendor_id : GenuineIntel
cpu family : 6

bogomips : 5000.23

About performance, here is the output of pveperf:

I have imported a Linux guest from a VMWARE server 2.0, converting the vmdk to a raw image with the command "qemu-img conver...".
The Linux guest is running debian 5 with kernel 2.6.26-2-amd64 #1 SMP Sun Mar 4 21:48:06 UTC 2012 x86_64 GNU/Linux and is now using 1 socket and 2 cpu (with the default qemu64 cpu type) and 2 Gb of RAM.
All is running well, but .... the Linux guest sometimes freeze and from the PVE control panel I can see the CPU going above 100% (I can read 120 - 130 % sometimes !?!?) and the only solution is to reset the guest.
I have updated the kernel, with the kernel coming from VMWARE, the VM freeze about every 5-10 minutes, now with the current kernel (without any trace of vmware-tools) the system is more stable, but I have the problem about 1 time a week...
Any idea ?
Best regards
