virt-manager storage options
when I am trying to create a new Xen domain guest, for example debian10 and Im trying to setup the new VM as using a STATA disk Im not able to select this option. Im giving the following: IDE, SCSI, Xen. In general there it should be presented as well SATA. But it missing in this case.
Check the screenshot attached.
AFAIK when using QEMU with Xen the emulated chipset is a PIIX which doesn't support SATA, and hence the option won't be available. This is not a limitation of libvirt or FreeBSD, but rather of Xen itself.
Note that however using IDE or SATA is not going to make much difference performance wise, it's all emulated by QEMU and hence slow. Your best option is to use the Xen PV drivers (usually called blkfront) in the guest in order to obtain the best performance, anything emulated is going to be slower.
