You did use 'iommu=soft' on your bootup line right? I thought I did; turns out I was wrong. Sorry for the noise. Now I tried with "iommu=soft swiotlb=force", but this way the guest immediately disappears; it doesn't even start to produce console output. # xm create -c f15-64bit-pv Using config file "/etc/xen/f15-64bit-pv". Using to parse /grub/menu.lst Started domain f15-64bit-pv # http://wiki.xen.org/xenwiki/XenPCIpassthrough says though: Bugs: # Starting the DomU using pvgrub with 'iommu=soft swiotlb=force' breaks pvgrub. Perhaps that could be the reason. Removing "swiotlb=force" and keeping only "iommu=soft" crashes (?) the same way. Thanks, lacos
