I followed the wiki[1] to create a KVM virtual machine using bridged network on CentOS 6.5. It seemed to work fine on initial setup. However, after a boot, it doesn’t auto-start the VMs, or at least, something has to timeout (a *very* long time, on the order of 15–30
minutes) before they can be started.

Shortly after boot, if I go into “virsh”, then do a “list”, it just hangs. Likewise, if I go into “virt-manager”, it just hangs
“connecting”.

Kernel version is: 2.6.32-431.29.2.el6.x86_64

Relevant package versions:

libvirt.x86_64 0.10.2-29.el6_5.12
libvirt-client.x86_64 0.10.2-29.el6_5.12
libvirt-python.x86_64 0.10.2-29.el6_5.12
python-virtinst.noarch 0.600.0-18.el6
virt-manager.x86_64 0.9.0-19.el6
virt-top.x86_64 1.0.4-3.15.el6
virt-viewer.x86_64 0.5.6-8.el6_5.3
qemu-img.x86_64 2:0.12.1.2-2.415.el6_5.14
qemu-kvm.x86_64 2:0.12.1.2-2.415.el6_5.14

CPU is a Xeon E3-1230v3. I have the virtualization setting enabled in the BIOS.

I googled on this, and saw a bunch of talk about two years ago regarding issues with the libvirt packages having a deadlock bug. But I think the versions of the relevant packages that I have installed are new enough to have fixes for that.

Anyone ever fought this before?

Thanks!
