qemu goes to 100%?
Here's a weird one I just noticed: I've been using a
Windows 10 virtual machine to run my tax software.
I've got it displayed in virt-viewer and all is
well, then I close the virt-viewer window and
leave the KVM running. About 5 minutes later I
see a cpu suddenly pegged at 100%. I run top and see
that qemu is the culprit. I start virt-viewer
again, and it goes back to normal.
Anyone else seen this? Why would nobody looking at
it make it go crazy I wonder?
