[PATCH v2 0/3] esx: Form URLs containing IPv6 addresses correctly
by Richard W.M. Jones 27 Jan '26

27 Jan '26

v1: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/YRCX… In v2, replace multiple VIR_DEBUG with just one, and add the Reported-by and Reviewed-by tags on the last commit. I'm sure this can't be the only place in libvirt that has to solve this problem (nor the "is this hostname IPv6" problem for that matter), but my searching skills are not good enough to find any other places.

[PATCH] bhyve: improve loader handling on arm64
by Roman Bogorodskiy 27 Jan '26

27 Jan '26

Bhyve on arm64 does not have the bhyveload(8) tool. That means that it cannot be used as a default if the loader is not configured for the domain. To prevent users from getting unusable configurations, handle loader configuration on arm64 like that: - if loader is specified in the domain XML, just use it - if not specified, try to check whether the default uboot loader is available on the system. In case it is, set is as the loader, otherwise fail with the error.

[PATCH 0/3] esx: Form URLs containing IPv6 addresses correctly
by Richard W.M. Jones 27 Jan '26

27 Jan '26

https://issues.redhat.com/browse/RHEL-138300 This bug requires a further fix to allow libvirt to access ESXi servers over IPv6. The way that we constructed the URL (for fetching things from the SDK with curl) was wrong. We formed URLs like: https://1234:56:0:789a:bcde:72ff:fe0a:7baa:443/sdk but with IPv6 we need to put [...] around the IPv6 address. The first patch just adds some debugging so we can see what URLs we are passing to curl. THe second patch is a bit of abstraction so that we're only creating URLs in one place (but two functions). The third detects if the server name is an IPv6 address and adds the square brackets as appropriate. Tested by me, by connecting to an IPv6 VMware server and listing all the domains, and getting the libvirt XML of a single domain. I didn't test all possible operations in depth. The bug was reported by Ming Xie. Rich.

[PATCH] qemu: migration: Call hook script on source host at migration start
by Guy Godfroy 26 Jan '26

26 Jan '26

Currently, the qemu hook script with the "migrate" operation is only called on the destination host at the beginning of incoming migration. This makes it impossible for the source host to prepare for migration, for example to change storage locks from exclusive to shared mode when using shared LVM storage with lvmlockd. Add a hook call on the source host at the beginning of outgoing migration. The hook is called with "source" as the extra argument to distinguish it from the destination hook which uses "-". The same change is also applied to the libxl driver for consistency.

[PATCH] Standardize socket family checks with proper macro
by Julio Faracco 23 Jan '26

23 Jan '26

There is a macro called VIR_SOCKET_ADDR_IS_FAMILY that checks the socket family. There are several occurrences of raw checks in libvirt code. This commit just standardizes the socket family checks by using its macro.

[PATCH v2 0/2] Remove @masked argument from virSocketAddrFormatWithPrefix
by Julio Faracco 23 Jan '26

23 Jan '26

Since its introduction in commit 426afc00, the function virSocketAddrFormatWithPrefix has never been called with argument masked=false. So, this commit proposes to remove this unnecessary argument from the function scope. This series also proposes the respective test cases for virSocketAddrFormatWithPrefix (now, without @masked argument).
