Hi Greg,

No all our VMs were Linux - we were pretty desperate (having both SSD and 
FusionIO storage to get deployed) and tried more or less every pre-built distro 
image out there along with all kinds of hand-built kernels (we're mainly a 
Gentoo shop). All to no avail. We weren't able to test further as we were at 
the brink of losing our customers, so there might very well have been things we 
could have done differently, but nothing that 3 months of googling and 
experimenting could uncover.

Best regards
