[libvirt] "virsh list" hangs
Hi, I am using RHEL 6.2 64bit, and the libvirt shipped in it is "libvirt-0.9.4-23.el6.x86_64". I found sometimes the command "virsh list" hangs forever, and same issue for virt-manager which is always in "Connecting" status. But after restarting the libvirtd service, this issue is gone. Is this a bug of libvirt? Any help will be appreciated. Thanks, Qian

I think I saw a bug in recent history about this, but now I can't find it. Anyway, please file a bug: https://bugzilla.redhat.com/ And attach debug logs. You can obtain them by editing /etc/libvirt/libvirtd.conf and setting: log_level=1 log_filters="" log_outputs="1:file:/var/log/libvirtd.log" For more information follow up http://libvirt.org/logging.html; For client log (we refer to virsh, virt-manager, ... as clients) you can set environment variables: LIBVIRT_DEBUG=1 LIBVIRT_LOG_OUTPUTS="1:file:client.log" virt-manager --no-fork Then attach /var/log/libvirtd.log and client.log to the bugzilla.

I think what happened to me is https://bugzilla.redhat.com/show_bug.cgi?id=757382 which is a dead lock issue between libvirtd process and its child process. It looks this issue has been fixed for Fedora 16, any plan for RHEL 6.2? Regards, Qian

If you'd like this to be backported to RHEL 6.2, perhaps the best thing to do is to open a support ticket to Red Hat specifically requesting that this Fedora BZ be cloned to RHEL. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
Thanks Eric. I'd like to know if this issue will be resolved in later release of RHEL (e.g., RHEL 6.3), if yes, I think I can wait. Regards, Qian

RHEL 6.3 will probably be based on 0.9.10, which already includes the fixes mentioned in bug 757382, so you are probably safe in waiting for that release. I'm not sure when the RHEL 6.3 public beta starts, but history of prior RHEL betas says it won't be much longer, if you'd like to give that a try. (It's hard to ever get a definitive answer out of engineers until an actual release occurs, because management has last say on what schedules can or cannot be met.)
