We've hit (probably) same bug in our buildsystem. I'm providing some info in an attachment. It seems to be happening at least on ppc and s390x archs. RHEL 7 libvirt-3.2.0-14.el7_4.3 kernel-3.10.0-693.5.2.el7 Bug not reproduced on: libvirt-3.9.0-14.el7_5.4.x86_64 virt-manager-1.4.3-3.el7.noarch qemu-kvm-rhev-2.10.0-21.el7_5.1.x86_64 Do shutdown/start on multi VMs in parallel, no deadlock. It may be related to this bug: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1688508 . It has been fixed according to "qemu: Fix shutting down domains in parallel -- If multiple domains were being shut down in parallel, libvirtd might have deadlocked. " in libvirt-v4.1 release note. (In reply to Han Han from comment #4) > Bug not reproduced on: > libvirt-3.9.0-14.el7_5.4.x86_64 > virt-manager-1.4.3-3.el7.noarch > qemu-kvm-rhev-2.10.0-21.el7_5.1.x86_64 > Do shutdown/start on multi VMs in parallel, no deadlock. > It may be related to this bug: > https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1688508 . It has been > fixed according to "qemu: Fix shutting down domains in parallel -- If > multiple domains were being shut down in parallel, libvirtd might have > deadlocked. " in libvirt-v4.1 release note. It's not related to that. Also can not reproduce with libvirt-3.2.0-14.el7_4.9.x86_64. Tomas, can you please test with libvirt-3.9.0-9.el7 or newer? My analysis shows that this bug might be a dup of 1536461. I'd like to close it as such. We've deployed libvirt-daemon-3.9.0-14.el7_5.2 and it seems to be fixed. Thanks! Very well, I'm going to put this into POST then so that we can test it. Verified on libvirt-4.5.0-2.virtcov.el7.x86_64 qemu-kvm-rhev-2.12.0-7.el7.x86_64:
1. Parepare a running VM with qemu-guest-agent active
(in vm)# systemctl status qemu-guest-agent
● qemu-guest-agent.service - QEMU Guest Agent
Loaded: loaded (/usr/lib/systemd/system/qemu-guest-agent.service; disabled; >
Active: active (running) since Tue 2018-07-10 16:30:30 CST; 4min 47s ago
Main PID: 723 (qemu-ga)
Tasks: 1 (limit: 1149)
Memory: 1.8M
CGroup: /system.slice/qemu-guest-agent.service
└─723 /usr/bin/qemu-ga --method=virtio-serial --path=/dev/virtio-por>
2. Create serval snapshots with --disk-only --quiesce
# virsh snapshot-create-as usb S1 --disk-only --quiesce
Domain snapshot S1 created
# virsh snapshot-create-as usb S2 --disk-only --quiesce
Domain snapshot S2 created
# virsh snapshot-create-as usb S3 --disk-only --quiesce
Domain snapshot S3 created
Check VM is running well. Verified.
I mistook the bug verify of https://bugzilla.redhat.com/show_bug.cgi?id=1598084 as comment11. Please ignore it.
