Hi,

for a few months i have use xen 4.2 unstable with pci passthrough and it was working fine, but i had problems with video drivers crashing in windows, so somewhere
i saw an alternative with vmware ESXI 5.0 server, i have tyred it and i was very successful, everything i wanted worked!
so after a few months of preparation and planing i went and install ESXI 5.1, ( it got updated ) but the pci passthrough is broken in 5.1, so i reverted to the 5.0 and
windows 7 with amd ati 6670 works! but i use zfs storage, so on opensolaris VM i had passthrough 3ware 9650SE-4LPML and 6 port intel sata raid, witch in the past
of the experimental stage it worked, but now, i can passthrough the devices, and it loads them fine, but cant access the disks!
