DAC & glusterFS - errors
by lejeczek
Hi guys
I'm trying to spin up a VM whose image is on a GlusterFS
vol, and I fail:
-> $ virsh create /var/lib/pacemaker/conf.d/win10Pro.xml
error: Failed to create domain from
/var/lib/pacemaker/conf.d/win10Pro.xml
error: failed to initialize gluster connection
(src=0x7f0af807b410 priv=0x7f0af8090070): Invalid argument
In logs:
...
2021-07-05 21:13:12.950+0000: 141524: warning :
virSecurityDACSetOwnership:828 : Unable to restore label on
'win10Pro.qcow2'. XATTRs might have been left in
inconsistent state.
internal error: child reported (status=125): failed to
initialize gluster connection (src=0x7f0b00097030
priv=0x7f0b000956c0): Invalid argument
Any ideas & suggestions greatly appreciated.

virsh qemu-monitor-command block_resize not working
by arjen-libvirt＠gugu.be
Hi List,
some version info:
]# /usr/libexec/qemu-kvm -version
QEMU emulator version 4.2.0
(qemu-kvm-4.2.0-48.module+el8.4.0+534+4680a14e) Copyright (c) 2003-2019

]# virsh version
Compiled against library: libvirt 6.0.0
Using library: libvirt 6.0.0
Using API: QEMU 6.0.0
Running hypervisor: QEMU 4.2.0
information about block devices for one specific guest:
]# virsh qemu-monitor-command uat-win201202.uat.gugu.be --hmp info block
libvirt-2-format:

Removable device: not locked, tray closed
But then, when I want to resize the block device, I just cannot seem to
find the correct device. I tried all of these:
virsh qemu-monitor-command uat-win201202.uat.gugu.be --hmp block_resize
libvirt-2-storage 48G
Error: Cannot find device=libvirt-2-storage nor node_name=

drive-virtio-disk0 48G
Error: Cannot find device=drive-virtio-disk0 nor node_name=
In a previous qemu version this worked (EL 7). Can someone help me out?

host identifier
by Jiatong Shen
Hello community,
I am using OpenStack nova and realize that nova now uses host fqdn from
libvirt as a uniq identifier for a compute node. The issue is that host
might need to change its fqdn under some
rare circumstances and lose some usage data due to the nova manages
compute node resources.
My question is: does libvirt already export host uuid identifier to other
applications? I skim through the code base and find there is host uuid
related code which reads /etc/machine-id to obtain a uniq uuid for
migration, but seems this uuid cannot be obtained through virsh interface.
Thank you for you help.
