Windows 2k8 R2 guest with updated virtio drivers is idle inside but on the host qemu-kvm process uses 7-15% cpu. Things that have been tried without any significant success - removed tablet device - manually set cpu topology for cores per socket Is it just me or the qemu-kvm has little tolerance with windows?

Hi All, I''m getting the attached panic in the hypervisor on a Sun 6270 running xen-testing.hg changeset 19913:6063c16aeeaa. I can run xen-3.3.1 from the standard SLES 11 distribution (which says that it''s changeset 18546 but it has many patches). Any ideas? thanks, dan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

...ck to normal with a run time at 150 secs. I''ve created an infographic from our ganglia graphs for the above scenario. https://dl.dropboxusercontent.com/u/23468442/misc/lustre_bc_overhead.png Attached is an excerpt from perf top indicating that the kernel routine taking the most time is _spin_lock_irqsave if that means anything to anyone. Things tested: It does not seem to matter if we mount lustre over infiniband or ethernet. Filling the buffer cache with files from an NFS filesystem does not degrade performance. Filling the buffer cache with one large file does not give degraded performa...

I''m currently working on moving storage services into their own domain and I''ve been looking at blktap2. I''ve been trying to get an image mounted with blktap2 and for some odd reason and tapdisk2 keeps hanging instead of quitting at the end. I haven''t removed any of the storage startup code at this point so everything should be as it normally is in xen-unstable.
