Specify different machine type in create.sh

[ghost]

When creating the VM XML configuration for virsh, the machine type pc-i440fx-focal is used, which is unavailable on Arch Linux and the create.sh script throws an error.

However, based on the output of virsh capabilities on Arch, it would seem that there is a generic pc option which should link to the latest pc-i440fx machine type. Would it be possible to use pc instead?

Example output from virsh for x86_64 on Arch:

      <machine maxCpus='255'>pc-i440fx-8.2</machine>
      <machine canonical='pc-i440fx-8.2' maxCpus='255'>pc</machine>

Changing machine to "pc" does, in fact, alias to "pc-i440fx".

<type arch="x86_64" machine="pc">hvm</type>

This allows successful creation of a Helios VM on Gentoo and should additionally work on any distro using QEMU 6.2 or later, as announced here.

Also tested and confirmed to still work on Ubuntu 20.04. It's using QEMU 6.28 apparently:
