Starting VM 'Debian Jessie 8.1 (64-bit)'
Internal error: xenopsd internal error: XenguestHelper.Xenctrl_dom_linux_build_failure(2, " panic: xc_dom_core.c:609: xc_dom_find_loader: no loader\"")

The same thing for me.
Doesn't work.

hey, roadancer and klukonin check your xenserver version, if you get such error, this means you still have 6.2

Fresh install of 6.5 has to be like this:

cat /etc/redhat-release
XenServer release 6.5.0-90233c (xenenterprise)

Why does this error happen, I need to install debian jessie on XCP 1.4.9 and I am not allowed to upgrade...
