[Rdo-list] Juno kvm/qemu fail to start after hypervisor reboot

Hi Has anyone encountered this problem? The VM comes up fine for the first time. But when hypervisor is rebooted, it never comes back online. Issuing a virsh start goes through series of checks but shuts off again. Only thing found from instance libvirtd/qemu log file is 2014-12-08 22:12:39.172+0000: starting up LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin QEMU_AUDIO_DRV=none /usr/libexec/qemu-kvm -name instance-0000001a -S -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off -cpu SandyBridge,+pdpe1gb,+osxsave,+dca,+pcid,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -m 8192 -realtime mlock=off -smp 2,sockets=2,cores=1,threads=1 -uuid 5433c5b8-c66c-4035-9208-9f5d24764cce -smbios type=1,manufacturer=Fedora Project,product=OpenStack Nova,version=2014.2-2.el7.centos,serial=fdd0e554-0105-4e8b-97e8-ec1fb11da4a9,uuid=5433c5b8-c66c-4035-9208-9f5d24764cce -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/instance-0000001a.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -no-kvm-pit-reinjection -no-hpet -no-shutdown -boot strict=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/dev/disk/by-path/ip-172.22.164.141:3260-iscsi-iqn.2010-10.org.openstack:volume-5613e627-c15a-4da9-8ffb-aac5e8660321-lun-0,if=none,id=drive-virtio-disk0,format=raw,serial=5613e627-c15a-4da9-8ffb-aac5e8660321,cache=none -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=25,id=hostnet0,vhost=on,vhostfd=26 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=fa:16:3e:16:5e:44,bus=pci.0,addr=0x3 -chardev file,id=charserial0,path=/home/ceph/nova/instances/5433c5b8-c66c-4035-9208-9f5d24764cce/console.log -device isa-serial,chardev=charserial0,id=serial0 -chardev pty,id=charserial1 -device isa-serial,chardev=charserial1,id=serial1 -device usb-tablet,id=input0 -vnc 172.22.164.139:0 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 Warning: option deprecated, use lost_tick_policy property of kvm-pit instead. char device redirected to /dev/pts/2 (label charserial1) qemu: terminating on signal 15 from pid 4067 2014-12-08 22:13:01.506+0000: shutting down The process 4067 is libvirtd itself. Tried with both qemu/kvm, local or volume, rhel guest and server images, the problem remains. Any clues appreciated. Regards, Rama
