New AppArmor denial

audit: type=1400 audit(1723503632.836:152): apparmor="DENIED" operation="open" class="file" profile="libvirt-aabe06c9-c0ff-4128-a956-6bc1fe37fabe" name="/proc/sys/vm/max_map_count" pid=6865 comm="qemu-system-x86" requested_mask="r" denied_mask="r" fsuid=64055 ouid=0

Probably from libvirt-daemon (10.5.0-1 -> 10.6.0-1) , needs confirmation. Already reported to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076946 . I sent some additional information there, reported upstream at https://gitlab.com/libvirt/libvirt/-/issues/660 and created #6733

And we have to do something about that bridge crash -- it's not a regression from the image refresh, it also affects c-files PRs and is at the top of the weather report. It also affects Arch BTW.

It reproduces locally:

for i in `seq 10`; do TEST_OS=debian-testing test/check-application TestFiles.testSorting $RUNC || break; done

But after fixing that, it crashes like this:

Fixed both in cockpit-project/cockpit#20880

[martinpitt]

It cleared up, but this TestMultiMachineVNC failure is persistent.

This is fortunately known. See cockpit-project/cockpit-machines#1764

Thanks!
