Kernel panics using 1.9

[deangreen4]

Hi,
not sure if this is just me but I have noticed a lot of kernel panic problems using prox 1.9
We have proxmox in production running about 200 VMs without issue and I built a new dev box for our guys. The new box is using AMDs, 24 cores and 64gb of RAM and now every VM that is built using more that 2 cores seems to kernel panic. OpenVZ containers are fine, just KVM has the problem.
To get round this I installed the old KSM kernel proxmox-ve-2.6.35 and now all works fine. I put this down to just this machine.
I just installed 1.9 on a 8 core Xeon server and saw exactly the same thing, I again installed the proxmox-ve-2.6.35 kernel and it cleared up.

Has anyone else seen these problems? As I am not going to upgrade the other production boxes to the new version if these problems will start on our production clusters

Cheers

Dean

Hi Tom,
it was just the basic 1.9 install. Sorry I havent got any further info on the panics really as I had to sort it there and then, as I did tonight. It either kernel panicked or got soft CPU lockups which caused massive problems and delays in the actual machine booting/building.
Not really a problem for me as we dont use openvz but I imagine it might be a pain for some of the folks that do want to use both visualization technologies
