Comment 2 Daniel Berrangé 2011-09-01 19:28:38 UTC

There are multiple fixes in upstream GIT. We need all of the changes to daemon/ and src/rpc which impact streams, upto and including this final change:

commit b3fb288e52b7d0a0e58ab0e0bcac970436832d04
Author: Daniel P. Berrange <berrange>
Date:   Wed Aug 31 17:42:58 2011 +0100

    Fix tracking of RPC messages wrt streams

Comment 7 dyuan 2011-09-07 07:50:49 UTC

Reproduced this bug with libvirt-0.9.4-7.el6, "virsh # start domain1 --console" will hang at the 3rd time.
Verified PASS with libvirt-0.9.4-9.el6, "virsh # start domain1 --console" run normally for 5 times. But there are still some errors in libvirtd.log at the guest "power down":

15:48:44.185: 10072: error : daemonStreamEvent:208 : stream had I/O failure
15:48:44.186: 10072: error : virFDStreamUpdateCallback:111 : internal error stream is not open
15:48:44.186: 10072: error : qemuMonitorIO:577 : internal error End of file from monitor
