Hello Sirs,
I buying a new server in a couple of days and I want to know if it's =
possible to do the following things (I'll use xen2 and netbsd3 as both =
dom0 and all domUs):
1) the server will be SMP with HT processors. is it possible to keep =
each domU on a physical CPU and each domU to use also HT (shorlty, every =
VM grounded to a physical CPU, while the kernel should see the 2 HT =
processors somehow) ?
2) Even more, is it possible to link every VM to a virtual HT processor =
? Should I be aware of any security issues in this case ?.
3) if the server will have 2 PCI SCSI controllers is it possible to use =
each one for single machine (shortly, domU1 should see and use only the =
first controller and use it's attached disks, and domU2 the second..) ? =
physdev_dom0_hide should do the trick, right ?
4) is it possible to use ALTQ in xen0 kernel in order to limit the =
unprivileged domains ?
5) is it possible to fix the xen networking interface names =
corresponding to each domU ?
--=20
Thanks,
Mihai
