[libvirt PATCH 0/4] increase locked memory limit when a vDPA device is present

by Laine Stump

We recently learned that vDPA devices may/will need to pin/lock all of guest memory, and so just as we do for VFIO devices, we need to increase the locked memory limit when a vDPA device is present. https://bugzilla.redhat.com/1939776 Laine Stump (4): conf: new function virDomainDefHasVDPANet() qemu: simplify qemuDomainGetMemLockLimitBytes() qemu: account for mdev devices in getPPC64MemLockLimitBytes() qemu: increase locked memory limit when a vDPA device is present src/conf/… [View More]

[PATCH v2] qemu: don't raise error upon interface update without <frames/> for <rx/> in coalesce

by Kristina Hanicova

With this, incomplete XML without <frames/> for <rx/> in coalesce won't raise error as before. It will leave the coalesce parameter empty, thanks to passing it as a parameter and return an integer to indicate error state - previously it returned pointer (or NULL for both error and incomplete XML).

[libvirt PATCH] conf: allow for a partial match when searching for an <interface>

by Laine Stump

Commit 114e3b42 modified virDomainNetFindIdx() to compare the alias name of the <interface> being matched (in addition to already-existing match of MAC address and PCI/CCW address). This was done in response to https://bugzilla.redhat.com/1926190 which complained that it wasn't possible to unplug an interface that had the same MAC address as another <interface> (which is the way interfaces are setup when using <teaming> - the "team" is identified in the guest virtio-net driver … [View More]by looking for another interface with the same MAC as the virtio-net device) - the reporter of that bug did not have PCI addresses of the devices easily available when attempting to unplug one of the two devices, and so needed some other way to disambiguate the two interfaces with matching MACs. Unfortunately, this caused a regression which was caught during QE testing - in the past it had been possible to use virDomainUpdateDevice (which also calls virDomainNetFindIdx()) to modify the alias name of an existing interface - with the change in commit 114e3b42 this was no longer possible (since we would try to match the new alias, which would of course always fail). The solution to this regression is to allow mismatched alias names when calling virDomainNetFindIdx() for purposes of updating a device (indicated by the new bool argument "partialMatch"). When calling for unplug the old behavior is maintained - in that case the alias name must still match. Because we need to keep track of potentially multiple "partial" matches so that we can go back later and try to disambiguate when necessary, I needed an array to hold the indexes of all the matches during the "first round". There is guidance in glib-adoption.rst saying that new libvirt code should prefer GArray/GPtrArray. A couple of adventurous souls have used GPtrArray, but so far nobody has used GArray, and I decided this was a good chance to try that out. It went okay. Reported-by: Yalan Zhang <yalzhang(a)redhat.com> Signed-off-by: Laine Stump <laine(a)redhat.com> --- I realized while writing this patch that an update-device test case in qemuhotplugtest would have caught this regression and so I probably should add such a test case to prevent it happening again, but the testing harness for update-device was only ever made to work for graphics devices, meaning there's some unknown amount of investigating and rejiggering that needs to be done to make such a test work (a quick attempt failed). Since someone is waiting on the fix for this regression, I'm hoping that I can get a reprieve on the "add a test case to catch thre regression" part that should accompany a bugfix like this in exchange for a promise that I will start looking into that immediately after I get this pushed (and then backported so testing of the bugzilla above can be completed) src/conf/domain_conf.c | 207 +++++++++++++++++++++++++-------------- src/conf/domain_conf.h | 2 +- src/libxl/libxl_driver.c | 4 +- src/lxc/lxc_driver.c | 6 +- src/qemu/qemu_driver.c | 6 +- src/qemu/qemu_hotplug.c | 4 +- 6 files changed, 145 insertions(+), 84 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 95602ae57e..f071bf93d0 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -16871,109 +16871,170 @@ int virDomainNetInsert(virDomainDefPtr def, virDomainNetDefPtr net) * virDomainNetFindIdx: * @def: domain definition * @net: interface definition + * @matchPartial: true if mismatched alias is still a match * - * Lookup domain's network interface based on passed @net - * definition.
