[libvirt] [PATCH] virt-host-validate: warn if kvm_hv is not loaded for POWER hosts
by Daniel Henrique Barboza 13 Mar '20

13 Mar '20

POWER hosts does not implement CPU virtualization extensions like x86 or s390x. Instead, all bare-metal POWER hosts are considered to be virtualization ready. For POWER, the validation is done by checking the virtualization kernel modules, kvm_hv and kvm_pr, to see if they are either not installed or not loaded in the host. If the KVM modules aren't present, we should not just warn but fail to validate. This patch implements this support. If kvm_hv is not installed, which can be determined by 'modinfo' returning not-zero return code, fail the verification. If kvm_hv is installed but not loaded, show a warning. The exception are POWER8 hosts, which can work with kvm_pr. In its case, ACK the use of kvm_pr if kvm_hv is not loaded/present.

[libvirt PATCH] docs: Fix blockCopy's documentation on --pivot & --abort flags
by Kashyap Chamarthy 13 Mar '20

13 Mar '20

The --abort and --pivot flags for ``blockjob`` are mutually exclusive — you either abort and keep the destination copy as a point-in-time "snapshot"; or pivot to the new copy. But you cannot specify both flags at once. Rephrase blockCopy's doc fragment to that effect.

[PATCH] apparmor: qemu load old shared objects
by Christian Ehrhardt 13 Mar '20

13 Mar '20

On qemu upgrades the old .so files usually are replaced. But on the other hand since a qemu process represents a guest instance it is usually kept around. That makes late addition of dynamic features e.g. 'hot-attach of a ceph disk' fail by trying to load a new version of e.f. block-rbd.so into an old still running qemu binary. Qemu adds a fallback to also load modules from a versioned directory in the temporary /var/run path. That way qemu is providing a way for packaging to store modules of an upgraded qemu package as needed until the next reboot. This change is allowing the qemu process access to these paths. Background: This is a continuation of a discussion at KVM Forum 2019 eventually becoming [1] and recently this change is queued to get into qemu properly [2].

[PATCH v2] conf: Don't generate machine names with a dot
by Michal Privoznik 13 Mar '20

13 Mar '20

According to the linked BZ, machined expects either valid hostname or valid FQDN (see systemd commit v239-3092-gd65652f1f2). While in case of multiple dots, a trailing one doesn't violate FQDN, it does violate the rule in case of something simple, like "domain.". But it's safe to remove it in both cases.

[libvirt PATCH] tests: fix double-lock of monitor in hotplug test
by Daniel P. Berrangé 13 Mar '20

13 Mar '20

The qemuMonitorTestNew() function returns with the monitor object locked, and expects it to still be locked when qemuMonitorTestFree is called. The qemuhotplug test, however, explicitly unlocks the monitor, but then forgets to lock it again. As a result the qemuMonitorTestFree function is unlocking a mutex it doesn't own. This bug has existed forever, but since we use normal POSIX mutexes and don't check the return value of pthread_mutex_lock/unlock we didn't see the error. It was harmless until the switch to the per monitor event loop which requires the thread synchronization to work reliably, whereupon it started crashing. Signed-off-by: Daniel P.

[PATCH v2 00/19] incremental backup: Handle bitmaps during block-commit

This is now based on top of a different implementation of the fix for late opening of backing chain during block-copy: https://www.redhat.com/archives/libvir-list/2020-March/msg00317.html Changes: - fixes suggested by Pavel - changes to capability use - rebased on master This series uses blockdev-reopen which was not yet stabilized in qemu, thus is experimental for now, but since incremental backup is experimental there's no problem with that. You can fetch the full branch along with patches for enabling the bits at: git fetch https://gitlab.com/pipo.sk/libvirt.git backup-commit You also need to use patched qemu which you can fetch from:
