Glenn, could you please give the attached patch a try?
It should be applied on top of the other correction, the old debug
patch should not be applied.
I have added some debug output to make sure we see what is happening.
This patch is included in kernel-xen-4.9.26-1
It should be in the repos now.
Still seeing the same issue. Without the extra debug patch all I see in
the logs after destroy is this...
xen-blkback: xen_blkif_disconnect: busy
xen-blkback: xen_blkif_free: delayed = 0
br0: port 2(vif1.0) entered disabled state
br0: port 2(vif1.0) entered disabled state
device vif1.0 left promiscuous mode
br0: port 2(vif1.0) entered disabled state
Without the dd running in the domU, the domU exits cleanly on destroy
and I don't see the busy message from above, eg
xen-blkback: xen_blkif_free: delayed = 0
xen-blkback: xen_blkif_free: delayed = 0
br0: port 2(vif5.0) entered disabled state
br0: port 2(vif5.0) entered disabled state
device vif5.0 left promiscuous mode
br0: port 2(vif5.0) entered disabled state
