[pve-devel] [PATCH qemu 0/1] fix qemu 2.9 drive mirroring to nbd target

[Alexandre Derumier]

Qemu 2.9 have implemented coroutine for drive mirroring
and it's currently buggy with nbd target.

When I test with big volumes (100-200G), mirroring always die
after some minutes.

This has been fixed in qemu 2.10.

Theses patches are coming from qemu-kvm-ev-2.9.0-16.el7_4.11.1
https://cbs.centos.org/koji/buildinfo?buildID=21003
(already backported from 2.10 to 2.9)
