[libvirt-users] logging of domains
Hi, recently i had some domains stopped without any obvious reason for me. Unfortunately i didn't find the cause. I'd like to log information about the domains that i have more information the next time this will happen. In /etc/libvirt/libvirtd.conf i have: log_level = 3 log_outputs="3:file:/var/log/libvirt/libvirtd.log" which creates enormous log files, but with logrotate and xz i can manage that. But i think this is just related to libvirtd. The logs for the domains under /var/log/libvirt/qemu are poor and very small, nearly no information. Is there a way to be more verbose with the domains so that i may find helpful information in these logs when the domains stop for the next time ? Thanks.

You can also create a snapshot of sda, but you need to specify the destination of the overlay manually e.g.: --diskspec sda,file=/path/to/sda.snap.qcow2 Libvirt just does not want to generate the filename for block devices since we can't know where to put the snapshot. signature.asc Description: PGP signature ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users

This is fortunate because external snapshots can be selected on a per disk basis: > > I understand, that it is not possible to make a snapshot of physical > device, but it is enough for me to take snapshot of vda.

[libvirt-users] Snapshot of single block device
Hello! I have a guest with one qcow2 disk image (vda) and one physical partition (sda) from host. When I'm trying to get snapshot with: virsh snapshot-create-as . It fails with message: error: unsupported configuration: source for disk 'sda' is not a regular file; refusing to generate external snapshot name I understand, that it is not possible to make a snapshot of physical device, but it is enough for me to take snapshot of vda. How to force virsh to ignore sda ? best regards Jarek ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
