[Kernel-packages] [Bug 1322441] [NEW] Windows guest unstable after random amount of time
Public bug reported: Ubuntu 14.04, all updates done as of 23/5/2014 Kernel : Linux 3.13.0-24-generic Qemu : 1.7.1 and 2.0.0 tested Tested using both Xeon 5620 and 5520 processors, 48GB RAM.

Guest appear to freeze intermittently (VNC console unresponsive, network pings dropped to guest, frozen IO) for 20-60 seconds at a time which repeats constantly every few minutes and guests do not recover unless QEMU is killed and the guest is started again.

[Kernel-packages] [Bug 1322441] Re: Windows guest unstable after random amount of time
The bug occurred when upgrading from 12.04.1 (3.2 kernel) to 14.04 (3.13 kernel). Booting with the old 3.2 kernel resolves the problem.

[Kernel-packages] [Bug 1322441] Re: QEMU Windows guest unstable after random amount of time
Tested with kernel - Linux 3.15.0-031500rc7-generic After 24 hours there's no sign of the problem. After watching numastat for a while I noticed that with the 3.13.0 kernel the allocated memory for qemu does a really sudden drop from 6GB down to 2GB. QEMU then freezes with 100% CPU until the allocation goes back up to 6GB again. On 3.15 the memory stays almost constant and is migrated towards one numa node as you'd expect. Just speculating but there must be some kind of page invalidation bug in the numa balancer. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1322441 Title: QEMU Windows guest unstable after random amount of time Status in “linux” package in Ubuntu: Incomplete Bug description: Ubuntu 14.04, all updates done as of 23/5/2014 Kernel : Linux 3.13.0-24-generic Qemu : 1.7.1 and 2.0.0 tested Tested using both Xeon 5620 and 5520 processors, 48GB RAM.
