I've confirmed that the template works on aarch64, but shouldn't the image for x86_64 be commented out if it is known to be broken?

It still may work on somebody's machine?

Thanks, LGTM

May, but sounds unlikely. It is easy enough to uncomment the image setting to try.

In the end we do want to know when it is working, and having to uncomment the image would give them a hint to let us know.

But if you want to merge as-is, then go ahead.

It did work in QEMU, on Linux

• CentOS Stream 10 guest kernel panic (invalid opcode: 0000 in chacha_8block_xor_avx512vl) #3022 (comment)

Maybe it would help to disable the AVX512 support in the cpuType (i.e. not use "host") and go for AVX2 only?

EL10 is known to not run on a lot of older Intel, which is why AlmaLinux re-enabled the support for "v2"

AlmaLinux OS Kitten includes an additional build using x86-64-v2

The same emulation issue also exists for centos-stream-9 (but didn't for centos-stream-8)

Fatal glibc error: CPU does not support x86-64-v2

cpuType:
  # Does not seem to boot with "qemu64"
  x86_64: "Haswell-v4"

One could choosing something lower, i.e. v2 or v3, since not all hosts have AVX512 support?

Edit: My bad, "Haswell-v4" does not mean x86_64-v4.

centos-stream-9

Let's fix this separately in:

• qemu: Intel on ARM: change the default CPU from qemu64 to something newer #3063
