Summary: [-next-20121129] memory leak/page allocator
fragmentation?
Product: Virtualization
Version: unspecified
Kernel Version: -next-20121129
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: kvm
AssignedTo: virtualization_kvm@kernel-bugs.osdl.org
ReportedBy: peter@hurleysoftware.com
Regression: No
With a single 2Gb/4-core VM on a 10Gb/8-core host, the _host_ ran out of 32kb
page blocks. I can't be certain that it was kvm because the OOM condition
triggered a GP fault in the SLUB allocator. (The other suspect is nouveau.)
I have attached the kernel log and a SysRq Show Memory dump of the machine
shortly after boot without running kvm.
