Hi there,

installed a fresh pve1.7 on i7-870, 16GB DDR3-1333, Adaptec2405 with RAID1 (no write-cache enabled)

Maschine is running very fast and everything is fine, i thought. But then this:

Whats happening here? Now i can't start my kvm maschines, i think i've to reboot the server. Or has it to do with HT, i gave my maschine 2 Cores, will try with only one.
 
sure, arghh....
sry, i forgot it

pveversion -v

Hi,
you don't wrote if you use OpenVZ. In this case you should try the 2.6.18-kernel.

why do i have to switch to 2.6.18? had containers running with 2.6.32

just had the same issue with 2.6.18 and kernel panics
