Description of problem: I'm using KVM with RHEL 5.5 ans sometimes when i force off a guest through virt-manager, i got this error every 10-15 seconds and i can't do any other activities until i shutdown all vms : #dmesg unregister_netdevice: waiting for vnet3 to become free. Usage count = 1 Sometimes, I'm not able to shut down all guest so i need to reboot :( Any idea on how i can fix that without doing a shutdown all guest or rebooting the host ? Version-Release number of selected component (if applicable): kvm : kvm-83-164.el5 virtmanager : 0.6.1-12.el5 How reproducible: 1. Boot a normal guest 2. Boot another guest on PXE, leave the guest in the pxe menu 3. Force off this guest (right click on the vm inside virt-manager - shutdown - forceoff) (you may have to do it couples of times (3-5) before you will get the unregister_netdevice error) Actual results: the host system hang (you can't start any other program I.E Firefox by example #dmesg unregister_netdevice: waiting for vnet3 to become free. Usage count = 1 Expected results: no error and no hang
Reassigning to kernel.
Please specify which kernel version you are using. Looks a bit like a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=584412 Does this still happen with this kernel: http://brewweb.devel.redhat.com/brew/taskinfo?taskID=2376934
I'm using kernel 2.6.18-194.el5 and it looks like the same bug mentioned in 584412. I will try with the kernel you have suggested and will let you know
