Package: ganeti-2.15
Severity: normal
Tags: upstream patch
Dear Maintainer,
Starting with version 2.6, QEMU will fail to start with an error when
aio=native and no cache=none is present. This is documented in
http://wiki.qemu.org/ChangeLog/2.6. QEMU has been complaining about this
since 2.3.
Attached is a patch that detects this in the hypervisor setup and force
the disk_cache setting, logging it at the same time. The patch verbatim
taken from
https://github.com/ganeti/ganeti/commit/1e510ccd092f472919a9f8b34ede838476ab7e2e.patch
