Good day!
I decided to try xen on a Linux server. I know that during installation, the kernel and the system itself change. The question is whether it will be possible to use the system as a valuable one, namely, to raise samba, cups, etc. on it ... whether this will affect the work of xen and guest OS.
UPD - there will be a terminal server with Windows 2008 on the guest - users will actually work in the terminals themselves (fully - Word, 1C7, browser, in general, like on a regular computer).

Yes, you can, if there is a high load on dom0, domU will also start to slow down.
PS: I have NFS up on dom0 and everything is OK.

Will lead normally. It's just a security hole. In the normal case, the host system only has a management interface on a separate vlan or eth. Or just direct access from the console.
During installation, only the hypervisor and management utilities are installed. Well, unless in your distribution support for xen was disabled during the build - then rebuild the kernel. So, all the code for running Dom0 and DomU has long been accepted into the kernel.
A separate question - what's the point of taking xen to run qemu? Windows, for obvious reasons, does not know how to use paravirtual mode, which means it will have to be run in HVM. I would immediately use a regular KVM.
