Bug Description
Hello,
I upgraded a Xen PV domU with Ubuntu 19.04 installed to 19.10. The domU is running on a Ubuntu 18.04 server with xen 4.9.2. The upgrade went fine, and I restarted the system as expected. But the domU want start. I use pygrub for the domU to start.
Here the config of the domU
-------
# Basics
name = "lisa"
memory = 2048
bootloader = "pygrub"
# Disks
disk = [
'phy:
'phy:
]
# Network Interface
vif = [
'bridge=xenbr0, mac=00:
'bridge=xenbr1, mac=00:
]
# Advanced
vcpus=2
-------
Here the output when I start the machine with xl:
-------
xl create /etc/xen/lisa.cfg
Parsing config from /etc/xen/lisa.cfg
xc: error: panic: xc_dom_
: Invalid kernel
xc: error: panic: xc_dom_core.c:702: xc_dom_find_loader: no loader found: Invalid kernel
libxl: error: libxl_dom.
libxl: error: libxl_create.
libxl: error: libxl_domain.

Hi Richard,
I found out that I can boot the domU if I change it to a HVM.
e. g. Comment the line
# bootloader = "pygrub"
and add the line
builder = "hvm"
in the config file.
Now the domU works as expected, but it is a HVM what brings several disadvantages and cost more resources. So I really hope the Ubuntu Team can fix the problem in xen/pygrub.
Thank you

I've had the same problem for a while now, similar setup as described on the forums:
https:/ /ubuntuforums. org/showthread. php?t=2431459& p=13913095# post13913095
I can boot the older 5.0.0 kernel if I'm fast enough with the console immediately upon creation of the DomU (i.e., xl create -c ...), but this makes unattended DomU start unachievable.
