For network have you tried to remove model in vif?
About disk if you have low performance with raw disk can be the blktap (if
installed), in this case uninstall it and will use upstream qemu qdisk
instead with big disk performance increase.
For vga try to use stdvga instead, cirrus is very old and with problem in
some cases.
If problems persist the problem will almost certainly pv drivers missing or
not working properly.

I hope that the information will be useful, sorry for my bad english.

Hit the send button too soon:

Disabling Xen platform PCI:

The driver loads but no ip address is assigned using DHCP (0.0.0.0).

Removing device model:

The driver fails to load.

Seems like enabling PCI and model=pcnet is the only way to go.

Modified configuration file:Â

builder='hvm'

vcpus='1'

memory='768'

disk=['/usr/img/gpt.raw,,hda,w']

name='VrooM'

vif=['mac=00:16:3e:01:01:01, bridge=xenbr0, model=pcnet']

boot='dc'

xen_platform_pci='1'

sdl='0'

vnc='1'

device_model_version="qemu-xen"

device_model_override="/usr/bin/qemu"
