[xenpreview-dev] vm-install: tap:aio instead of file

[Gerd Bavendiek]

Hi,

according to the docs file backed virtual block devices should be 
avoided, if heavy IO may occur. Use never sparse files here - so I read 
on xen-users and: tap:aio should be preferred in such cases.

My question: Can this be done with vm-install ?

If yes, how ?

If no, how can it be done manually (I tried, replacing file with tap:aoi 
in a working configuration - boot froze) ?

Kind regards

Gerd
