virt. mgr. version: virt-manager-0.9.0-19.el6.x86_64 the upstream version is affected by the same issue. The solution seems to be in the usage of the virConnectSetKeepAlive API so the libvirt client (virt-manager in this case) keeps regularly pinging the server and be able to detect a dropped connection. fixed upstream with these patches: commit 0c95a5e725256f552774db05cc2fa3bee3b1a25e Author: Giuseppe Scrivano <gscrivan> Date: Tue Jul 1 15:01:58 2014 +0200 console: prevent access to deleted objects last commits revealed that some objects can still be accessed by registered callbacks after the console is closed. Unregister these callbacks.

Hi,Jiri Prajzner I am confused by the steps in description,what do you mean in step 3:Drop the connection on VM(s) side. I only can reproduce the bug by adding a remote connection,open a guest console,then destroy the network in remote host,then virt-manager freeze.

I have evaluated the backport and unfortunately it doesn't apply cleanly in the virt-manager version we ship in RHEL-6. I would prefer to not introduce new changes that are not already tested to address a non-serious issue like this one at a so late stage in the RHEL-6 development. Please re-open if you disagree with this decision. |
