<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Ok but I am going through libvirt instead of xenapi since I am just using a debian + xen-hypervisor package.<BR>
<BR>
Also going through libvirt seems to be better, since it doesn’t make your setup as “strongly” connected to xen.<BR>
<BR>
For those using the following in debian/ubunbu would the usage of the xenapi still work?<BR>
<BR>
ii libxenstore3.0 4.0.1-2 Xenstore communications library for Xen<BR>
ii linux-image-2.6.32-5-xen-amd64 2.6.32-35 Linux 2.6.32 for 64-bit PCs, Xen dom0 support<BR>
ii xen-hypervisor-4.0-amd64 4.0.1-2 The Xen Hypervisor on AMD64<BR>
ii xen-qemu-dm-4.0 4.0.1-2 Xen Qemu Device Model virtual machine hardware emulator<BR>
ii xen-utils-4.0 4.0.1-2 XEN administrative tools<BR>
ii xen-utils-common 4.0.0-1 XEN administrative tools - common files<BR>
ii xenstore-utils 4.0.1-2 Xenstore utilities for Xen<BR>
<BR>
Since I thought xenserver was a separate product?<BR>

I believe the work around Vish is referring to is made in nova.conf:<BR>
--xenapi_remap_vbd_dev=true<BR>
<BR>
Give that a go, hopefully gets you on your way!<BR>
