[Qemu-devel] blockcopy qemu fail and libvirt

[Vasiliy Tolstov]

Hi, i'm use qemu 2.4.0 and libvirt 1.2.16 and try blockcopy to migrate vm disk

virsh -c qemu+ssh://address@hidden/system blockcopy domain sda /dev/nbd2
--wait --pivot

libvirt says:
Successfully pivoted
2015-12-01 14:37:18.188+0000: 18288: info : libvirt version: 1.2.16
2015-12-01 14:37:18.188+0000: 18288: warning :
virEventPollUpdateTimeout:268 : Ignoring invalid update timer -1

but virsh command returns zero exit code

qemu blockcopy failed and target device contains zeroes.

i see some qemu git commits about block/migration and block that can
fix this isse, does qemu-devs confirm that this bug is fixed?

Also libvirt devs - do you know about this libvirt issue (when virsh
doing blockcopy and qemu process does not success complete blockcopy)
?
