[Qemu-devel] [Bug 1338277] Re: Ubuntu 14.04 + QEmu 2.0 + KSM = 1, makes Windows 2008 R2 guests to crash (BSOD)

2014-07-07 Thread Matthew Anderson
Hi Thiago, Your issue probably isn't related to the one I reported [1322441]. My issue was with automatic NUMA balancing. You could certainly try disabling numa balancing ( echo 0 > /proc/sys/kernel/numa_balancing ) and enabling KSM again to see if the fault occurs and if the crash is resolved it

[Qemu-devel] BUG: RTC issue when Windows guest is idle

2013-02-21 Thread Matthew Anderson
If this isn't the correct list just let me know, I've run into a bug whereby a Windows guest (tested on Server 2008R2 and 2012) no longer receives RTC ticks when it has been idle for a random amount of time. HPET is disabled and the guest is running Hyper-V relaxed timers (same situation withou

2012-04-30 Thread Matthew Anderson
Public bug reported: I've been having a consistent problem booting 2008R2 guests with 4096MB of RAM or greater. On the initial boot the KVM process starts out with a ~200MB memory allocation and will use 100% of all CPU allocated to it. The RES memory of the KVM process slowly rises by around 200m
