If it's just for /boot, I wouldn't expect much of a difference. It sounded like you wanted to install the OS on a flash drive. Still, booting from RAID 1 isn't generally a problem. Start the first partition (/boot) at 1 megabyte for best alignment and install grub on both drives. I won't suggest that booting from flash is wrong, but there really aren't any advantages. > The host will be Gentoo, i haven't decided about the guest yet.

The answer depends a lot on what you use for virtualization. It doesn't sound like anyone who's answered has done virt on a Soekris. Support in the CPU isn't enough by itself. I'd be somewhat surprised if you could do hardware virt on a 6501. If you use Xen and paravirt, ignoring hardware virt, the guest would probably be responsive enough. Bear in mind that you'll want to minimize overhead in any way that you can. The biggest overhead in most virtualization setups is disk storage. If you use an LVM to provide backing for your guest, you'll see a huge performance benefit relative to using file backed storage. _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
