I'm using Gentoo. Kernel packages < 2.6.32-r7 (Release 7 not RC-7) have had this problem. Haven't tested -r8 to -r10. Kernel 2.6.32-r11 is currently working fine. 2.6.34 was working too but it crashed after two days with a clock syncing issue. I'm hopping that 2.6.32-r11 doesn't have this issue. It's currently running for 24 hours now. KVM is 0.12.4. - Robert On 06/22/10 14:32, Thomas Besser wrote: > Thomas Besser wrote: >>> On Wednesday, 16 June 2010 17:14:54 +0300, >>> Avi Kivity wrote: >>>> 2.6.26 is really old.
