Comment 9 for bug 1935617

Since the bare metal case reports a memory issue on the crashes, let us give it a bit more memory - with 2G it works finally.

Instead of the other tests in launchpad/canonistack this uses KVM mode via "-machine accel=kvm -enable-kvm -cpu host". Switching that instead to "-machine accel=tcg" it fails the same.

But I found what consumed all the memory, the guest is (by default) started with the same CPU set as the host which means -smp 156. Disabling SMT in general on the host and starting the guest with 4 cpus allows to reduce the memory to 1G (but 512M still fails). Some other environment detail seems to bump the memory demand up.

As a cross check I can it on canonistack with 2G but it still fails with the segfaults.

With the adapted config it worked in qemu 5.2 in KVM and TCG mode.
