(In reply to Li Xiaohui from comment #0) > Steps to Reproduce: > 1.1 on host: > # /usr/libexec/qemu-kvm -M pc -cpu SandyBridge -enable-kvm -m 2G -smp 4 > -nodefconfig -rtc base=utc,clock=host,driftfix=slew -device ... -vnc :2 > -monitor stdio -device ... Can you give the full QEMU command line which was used? The backtrace is in spice code, but the command line is missing the spice bits (ie qxl is probably used). Which version of spice-server are you using on the host? Which linux guest do you use for the testing, in particular on the 4th guest?

Which version of spice-server are you using on the host? > Which linux guest do you use for the testing, in particular on the 4th guest? 1. qemu command line like this（different guest only vnc port and mac address are different）: /usr/libexec/qemu-kvm -M pc -cpu SandyBridge -enable-kvm -m 2G -smp 4 -nodefconfig -rtc base=utc,clock=host,driftfix=slew -device virtio-scsi-pci,id=scsi0,disable-legacy=on,disable-modern=off,iommu_platform=on -drive file=/home/rhel7.6.qcow2,if=none,id=drive-scsi0-0-0-0 -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0 -vnc :2 -monitor stdio -device virtio-net-pci,mac=08:9e:01:c2:65:82,id=jsalaf,vectors=4,netdev=id879abc,bootindex=1 -netdev tap,id=id879abc,vhost=on -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 -chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 -device virtserialport,bus=virtio-serial0.0,chardev=qga0,id=qemu-ga0,name=org.qemu.guest_agent.0 -vga qxl 2.spice-server version used on host: spice-server-0.14.0-4.el7.x86_64. 3.now use the 4th guest for test and found the bug. but also don't rule out the existence of bug on the first three guest Looking at the paths this is possible looks like the guest can easily trigger this. Maybe we should just give a warning. Posted upstream a patch. See https://lists.freedesktop.org/archives/spice-devel/2019-June/049381.html Merged https://gitlab.freedesktop.org/spice/spice/commit/bf968572d1f7a0052df2615b69b361b0ec652a29 upstream, should not be hard to backport. too late for 7.7, moving to 7.8 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Created attachment 1441012 [details] script "time-warp-test" Description of problem: With 3 guests running 'time-warp-test' script firstly, the fourth guest start later than them sometimes will quit from qemu-kvm process when reboot Version-Release number of selected component (if applicable): For host: kernel-3.10.0-889.el7.x86_64, qemu-kvm-rhev-2.12.0-2.el7.x86_64 For guest: kernel-3.10.0-889.el7.x86_64 How reproducible: 5/5 Steps to Reproduce: 1.Boot 3 linux guests, and with keep 'time-warp-test' script running at the same time. 1.1 on host: # /usr/libexec/qemu-kvm -M pc -cpu SandyBridge -enable-kvm -m 2G -smp 4 -nodefconfig -rtc base=utc,clock=host,driftfix=slew -device ... -vnc :2 -monitor stdio -device ... 1.2 on each guest: # gcc -Wall -o time-warp-test time-warp-test.c -lrt # ./time-warp-test 2.After step 1, boot the fourth linux guest(like 1.1). After guest start successful, then reboot it(maybe need some times) Actual results: (process:39388): Spice-WARNING **: display-channel.c:2431:display_channel_validate_surface: canvas address is 0x5555583bbb08 for 0 (and is NULL) (process:39388): Spice-WARNING **: display-channel.c:2432:display_channel_validate_surface: failed on 0 (process:39388): Spice-CRITICAL **: display-channel.c:2035:display_channel_update: condition `display_channel_validate_surface(display, surface_id)' failed Detaching after fork from child process 40476.

Additional info: QE will test linux guest and older qemu-kvm version later. and update test result to bz asap.
