Comment 2 for bug 1297224

Thanks for your reply.
I not tried xen trusty package for now but only a fast watch on debian folder of packages source.
seabios and upstream qemu is not specified on configure for what I saw (./configure --enable-xend --prefix=/usr) and I think should be done to have seabios and upstream qemu without adding distro patches (I saw at least 3 patches about them), same for ovmf if you will add it (but actual ovmf trusty package seems too old for good xen support, if I remember correctly the patch for a decent xen support are ovmf upstream from the beginning of February).
About xend if you already shown that it is deprecated and will be removed okay, on xen 4.5 (on development) xend has already been removed.
About disks part from a fast watch seems ok but I have not tried it yet I do not have the certainty.
