Re: [PATCH 1/6 TEST-ARTIFACTS] Add a QTB container to run the Xen riscv64 tests

[Baptiste Le Duc <baptiste.le-duc@xxxxxxxxxx>]

Apologies for the broken threading, my SMTP relay rewrote the
Message-IDs. Cover letter is here:
https://lore.kernel.org/xen-devel/1786377707.8631fc262581453bbf619ec5b2062170.19fec689f7e000e099@xxxxxxxxxx/T/#u

Kind regards,
