Bug Description
Currently uvtool sets no cpu at all.
That works as it is defined as the most compatible old qmeu64 type - that has the attribute to be "emulatable" so you could migrate it into a TCG based qemu.
But that is nothing anyone wants, instead we loose more and more features/speed by having such an old default.
host-model will be "as close as possible to the host cpu" while at the same time avoiding the issues of host-passthrough which is non-migratable and potentially dangerous features.
Host-model would be a nice default for uvtool that I'd like to implement in our templates.
Unfortunately too late for focal, but there always is a next release ...

+1 as a new default
Would it be useful to retain the current default as an option?
