[PATCH 0/3] ci: Drop Alpine-314 and Debian-10
by Peter Krempa 05 Aug '22

05 Aug '22

Alpine-314 was dropped by lcitool recently. Debian-10 will reach EOL in August, so patches 2-3/3 should be pushed only after the upcoming release.

[PATCH V2 0/4] Handle physical address bits
by Jim Fehlig 04 Aug '22

04 Aug '22

Hi All, This is a V2 of Dario's old patches adding support for specifying the virtual CPU address size in bits https://listman.redhat.com/archives/libvir-list/2020-October/210901.html I've rebased those patches to latest master and tweaked them a bit. E.g. I removed the qemucaps code since phys-bits and host-phys-bits have been around before the minimum qemu version supported by libvirt. I also added patches to expose the number of host address bits and ensure ABI stability as requested in the old review comments.

[libvirt PATCH 0/2] fix console device access in ch driver
by Praveen K Paladugu 03 Aug '22

03 Aug '22

Patch1: Drops the check to only have a console/serial device configured for ch VMs. This is no longer needed. Patch2: Addresses https://gitlab.com/libvirt/libvirt/-/issues/344. Libvirt adds compat console devices for "hvm" VMs. The added console/serial device type is initialized to VIR_DOMAIN_CHR_TYPE_NULL, when in fact the device added is a pty device. This patch modifies the default console device type to "pty". I looked at NOT adding Compat Console devices for ch VMs. But this looked like a better fix.

Can RHEL7 VM run remote libvirt commands to Fedora36 host?
by Carol Bouchard 01 Aug '22

01 Aug '22

I have a test environment that use to work but no longer does. My laptop is Fedora36 (libvirt version 8.1.0.2) while the VMs it spawns are RHEL7 (max libvirt version is 4.5.0). The source of my problem seems to be that RHEL7 libvirt needs rw socket /var/run/libvirt/libvirt-sock which no longer exists in fedora36. The following is successful from RHEL7 VM to laptop: virsh -d0 --connect 'qemu+ssh://192.168.120.1/system?*socket*=/var/run/libvirt/libvirt-sock-ro' domstate beaker-test-vm1.beaker If I change the action from domstate to start, it fails on error: Failed to start domain beaker-test-vm1.beaker error: operation forbidden: read only access prevents virDomainCreate which made me realize ro stands for read-only; however, there is no libvirt-sock. I tried some of the other socket files without success. Is there a work-around? Carol

[libvirt] Semantic change in v4.3 slows down image creation and snapshots (on ZFS)
by Christian Ehrhardt 31 Jul '22

31 Jul '22

Hi, when discussing bug [1] triggered by [2] Daniel and I have found that the change [3] which is in since v4.3 was a semantic change to the behavior of libvirt. virt-manager used and still does issue a volume XML like: <volume> <name>disk.qcow2</name> <capacity>16106127360</capacity> <allocation>16106127360</allocation> <target> <format type="qcow2"/> <features> <lazy_refcounts/> </features> </target> </volume> Up until the commit above that was using preallocation=metadata, but now uses preallocation=falloc. In many cases (read: Fileystems) that won't be very user-visible, but if you are running on ZFS (or anything else that can't fallocate well) this is made worse by [4] slowing down these operations a lot. After the POV for virt-manager seems to have settled on the bug [1] referenced the remaining question is if libvirt should revert/modify the change [3] - and that we agreed required a wider discussion to be had here, hence this mail.
