I've just gotten everything switched to fedora 27, and I'm now finding that guestmount fails on a running VMs disk image. I used to be able to mount --ro and see a read only snapshot of the disk even if the KVM was still running. Now I get a lot of errors when I run: LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 guestmount -d centinil -i --ro mnt One of the errors that appears is: qemu-img: /tmp/libguestfssn6HDK/overlay1.qcow2: Failed to get shared "write" lock Is another process using the image? And, yes, another process is using the image, but --ro used to work even when that was the case. Should I submit a bug on this, or is this change deliberate? (The guestmount does seem to work fine once the VM is shut down). _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
