Package: src:ganeti
Severity: wishlist
Dear Maintainer,
The ganeti packages are available for arm64, but they are not fully
functional, as they have some x86 and PCI assumptions. That said, there
are not many things to fix to get it working. It basically needs a
wrapper to mangle the qemu arguments and to abuse the kvm_extra option
to create the flash devices.
You will find attached a wrapper for qemu-system-aarch64 to mangle
option. In addition, the following options are needed for the instance:
cpu_type: default (host)
kvm_extra: -drive
file=/usr/share/AAVMF/AAVMF_CODE.fd,if=pflash,format=raw,unit=0,readonly=on
-drive file=/shared/path/nvram/machine-name_VARS.fd,if=pflash,format=raw,unit=1
It would be nice if at some point those changes can be done directly
into ganeti.
Thanks,
Aurelien
