[v2] qemu: Substract isolcpus from all online affinity

[PATCH v2 0/4] qemu: Substract isolcpus from all online affinity

Posted by Michal Privoznik 1 year, 9 months ago

v2 of:

https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/4V7OI5AEGYRN4GFQMQPIN4MYPJNK3NYJ/

diff to v1:
- Don't error out on systems where /sys/devices/system/cpu/isolated is
  unavailable.
- Don't error out on systems where /sys/devices/system/cpu/isolated is
  empty.

Both of these resulted in new patches.

Michal Prívozník (4):
  virbitmap: Introduce virBitmapParseUnlimitedAllowEmpty()
  virfile: Introduce virFileReadValueBitmapAllowEmpty()
  virhostcpu: Introduce virHostCPUGetIsolated()
  qemu: Substract isolcpus from all online affinity
