Where can I find the list of valid arch's for virt-install?
Hmm, yeah, it seems the --arch argument doesn't support the usual method
for enumerating possible values (which to be fair, the man page says *some*
suboptions support that):
$ virt-install --arch=?
ERROR Host does not support any virtualization options for architecture '?'
I think something like this is a reasonable fallback:
$ virsh capabilities | xmllint --xpath '//arch/@name' -
name="alpha"
name="armv6l"
name="armv7l"
name="aarch64"
name="cris"
name="i686"
name="m68k"
name="microblaze"
name="microblazeel"
name="mips"
name="mipsel"
name="mips64"
name="mips64el"
name="ppc"
name="ppc64"
name="ppc64le"
name="riscv32"
name="riscv64"
name="s390x"
name="sh4"
name="sh4eb"
name="sparc"
name="sparc64"
name="x86_64"
name="xtensa"
name="xtensaeb"
A related question is, if I also specify `--cpu host` to ensure the
host cpu's ISA's are available to the vm, then will that conflict with
the `--arch arch` option?
I don't know for certain, as I haven't tried, but I'd guess that'd be
fine if the host and the guest are the same (e.g., amd64 host, amd64 guest.)
Someone more knowledgeable will probably weigh in with a more conclusive
answer.
