libvirt users - Nov 2017 - Re: Urgent: virsh - change-media run into a promptly close of libvirt

Hello,

I use the virsh change-media command and since the combination of:

etcsvms5:/kvm/CS8400/M1 # virsh version
Compiled against library: libvirt 3.9.0
Using library: libvirt 3.9.0
Using API: QEMU 3.9.0
Running hypervisor: QEMU 2.10.1

etcsvms5:/kvm/CS8400/M1 #

I got the following problem:

----------------------

etcsvms5:/kvm/CS8400/M1 # virsh change-media S5VCS84M1-VLP0 hdc --eject
Successfully ejected media.

etcsvms5:/kvm/CS8400/M1 # virsh change-media S5VCS84M1-VLP0 hdc 
/home/kvm/etcsdvmb/Medien/V7.0A/CS_licenses/key-cd_VCS85FTSVTL.iso --insert
error: Disconnected from qemu:///system due to end of file
error: Failed to complete action insert on media
error: End of file while reading data: Input/output error

----------------------

journalctl -b | less shows the following:

Nov 14 10:11:32 etcsvms5 kernel: libvirtd[10178]: segfault at 10 ip 
00007f49ff969170 sp 00007f4a069cb940 error 4 in 
libvirt_driver_qemu.so[7f49ff8d9000+172000]
Nov 14 10:11:37 etcsvms5 systemd-coredump[42152]: Process 10177 
(libvirtd) of user 0 dumped core.

----------------------

At the end all open consoles of all virtual machines closed and the 
virt-manager also.
A restart of the libvirtd is possible but not helpful

The virsh change-media commands are in procedure andused since a long time.
I need the change-media function at the installation of our test systems.
Therefor I need an urgent help please

Best regards

Holger

Seeing the stack trace of libvirtd will be key to identifying the bug. With
any luck systemd-coredump will have captured that. So can you run
'coredumpctl'
to get the stack trace it saved.

Then I'd suggest filing a bugzilla ticket against libvirt with the resulting
info so we have a record of it.

Regards,
Daniel
