Hi Michal Build with the latest libvirt source code, I found failed to spawn a qemu process, not sure if something wrong with my environment, can you please help to take a look at it? After build the latest (3.0.0) libvirt, found failed to start an existed domain. root@s2600wt:/home/taget/qemu# virsh start kvm02 error: Failed to start domain kvm02 error: internal error: Process exited prior to exec: libvirt: QEMU Driver error : Unable to move /dev/mqueue mount: Invalid argument then I found you had some code get merged, and required to use /dev/mqueue so mount it then start the domain again: mount -t mqueue none /dev/mqueue root@s2600wt:/home/taget/qemu# virsh start kvm02 error: Failed to start domain kvm02 error: An error occurred, but the cause is unknown some debug log are: … 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/var/run/libvirt/qemu/kvm02.dev/ mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakeParentPath:2971 : path=/var/run/libvirt/qemu/kvm02.dev//hpet 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/var/run/libvirt/qemu/kvm02.dev/ mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakeParentPath:2971 : path=/var/run/libvirt/qemu/kvm02.dev//vfio/vfio 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/var/run/libvirt/qemu/kvm02.dev//vfio mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/var/run/libvirt/qemu/kvm02.dev/ mode=0777 2017-01-05 07:48:44.195+0000: 37227: info : virObjectUnref:259 : OBJECT_UNREF: obj=0x7f7dc812fad0 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllDisks:7076 : Setting up disks 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllDisks:7085 : Setup all disks 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllHostdevs:7124 : Setting up hostdevs 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllHostdevs:7131 : Setup all hostdevs 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllChardevs:7155 : Setting up chardevs 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllChardevs:7163 : Setup all chardevs 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllInputs:7231 : Setting up disks 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllInputs:7238 : Setup all disks 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllRNGs:7270 : Setting up RNGs 2017-01-05 07:48:44.195+0000: 37227: debug : qemuDomainSetupAllRNGs:7278 : Setup all RNGs 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev/pts mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev/shm mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev/mqueue mode=0777 2017-01-05 07:48:44.195+0000: 37227: debug : virFileMakePathHelper:2899 : path=/dev mode=0777 2017-01-05 07:48:44.195+0000: 37227: info : virObjectUnref:259 : OBJECT_UNREF: obj=0x7f7dc812fad0 2017-01-05 07:48:44.195+0000: 37227: info : virObjectUnref:259 : OBJECT_UNREF: obj=0x7f7dc812fad0 2017-01-05 07:48:44.195+0000: 37227: debug : qemuProcessHook:2693 : Hook complete ret=0 2017-01-05 07:48:44.195+0000: 37227: debug : virExec:699 : Done hook 0 2017-01-05 07:48:44.195+0000: 37227: debug : virExec:736 : Setting child uid:gid to 0:0 with caps 0 2017-01-05 07:48:44.195+0000: 37227: debug : virCommandHandshakeChild:435 : Notifying parent for handshake start on 25 2017-01-05 07:48:44.195+0000: 37227: debug : virCommandHandshakeChild:443 : Waiting on parent for handshake complete on 26 libvirt: error : libvirtd quit during handshake: Input/output error 2017-01-05 07:48:44.216+0000: shutting down, reason=failed /\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ I work on the latest libvirt git tree. commit 866641d4c5706413393913fdb3bb1cd077683d21 Author: Michal Privoznik <mprivozn@xxxxxxxxxx> Date: Sat Dec 24 17:55:48 2016 +0100 NEWS: Update after qemu namespace fix Signed-off-by: Michal Privoznik <mprivozn@xxxxxxxxxx> Best Regards Eli Qiao(乔立勇）OpenStack Core team OTC Intel. -- |
