Yes, something like that, whatever fits.

Ok, now xen dom0 services start. I configured with './configure --enable-systemd ...'.

Another question that does not leave my mind is this.

I specified the '--with-system-qemu=/usr/local/bin/qemu-system-x86_64'

option for configure.

But now when I start I hvm guest with default parameters (builder=hvm)

in the 'ps -ef' output I xen's qemu-dm as the device modile for my hvm

guest. Why is that happening? I have a good qemu installation from sources

which I built with '--enable-xen' option.

Same thing actuallu happens with the system seabios. I've got an

installation os the seabios from sources made by my self.

I specified the '--with-system-seabios=/usr/local/share/seabios/bios-1.7.5.bin'

for configure. But I am not sure that the xen's installation is actually using it.

Are these options really have any effect?

No, I tried to say that usbbk and xen-scsibk is available in such
kernel, even if its not upstream.

It depends, if the systemd devel packages are installed they will be
used automatically.
