Its very, very hard to put a 'rule of thumb' to something like this. A
little info about your setup, or setup you are contemplating would help.
I don't see how the Hard disk / RAM type can change the performance penalty. can you explain why for example sata will have more penalty then SCSI ?

The system im building up will be a server with 6 SCSI 15k RPM disks.
2 will be used as RAID 1 and 4 as RAID 10.
It will be probably an IBM server.

Hello

What performance penalty I should expect from the I/O under domU ?
Does it matter to the I/O if the CPU has hardware virtualization ?

Thanks
