Public bug reported:
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:/dev/systems/lisa-root,xvda,w',
'phy:/dev/systems/lisa-swap,xvdb,w',
]
# Network Interface
vif = [
'bridge=xenbr0, mac=00:16:34:45:1F:A2',
'bridge=xenbr1, mac=00:16:3E:AE:D6:3F',
]
# Advanced
vcpus=2
--------------------------------------------------------------------------------------------
Here the output when I start the machine with xl:
--------------------------------------------------------------------------------------------
xl create /etc/xen/lisa.cfg
