https://bugzilla.kernel.org/show_bug.cgi?id=42635 --- Comment #3 from Klaus Mueller <kmueller@xxxxxxxxxxx> 2012-04-03 07:27:43 --- Meanwhile I detected, that using the boot option iommu=pt (or additional iommu=1) shows the same problem (regardless of suspend/resume). If the VM is started after the first virsh start / virsh shutdown cycle with virsh start again, the device is dead in the VM. Host must be rebooted to get it working again. If the options iommu=pt (or additional iommu=1) are not used at all, the VM can be restarted without any problem coming up. 1. Host booted w/ iommu=pt iommu=1 2. virsh start 3. virsh shutdown 4. virsh start 5. -> Passed through device in VM is dead. 1. Host booted w/o iommu=pt iommu=1 2. virsh start 3. virsh shutdown 4. virsh start 5. -> Passed through device in VM is fine. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
