Re: Unable to puzzle through grub.xen_pvh
Hello,
this link below is the first good analysis I've seen of how to write a grub2 script with xen support:
written by Hans V. K. now of the Debian-xen team.
cheers,

Normally, if you have a direct kernel boot, it becomes necessary to pass a few other options.
My experience booting Xen directly with a kernel is not much but with Qemu you need to pass a root. This usually is what will be mounted at '/'.
Coincidentally enough, there is such an option with Xen, too seen below

I was able to build and copy over the resulting built component. I then
proceeded to change an existing vm that booted PVH with the
kernel="/path/to/grub.xen_pvh" instead of bootloader="pygrub"
It worked in that I got a grub command prompt, which usually happens
when grub doesn't know what to do. I feel like I'm really close!
my cfg:
=============
name="hass"
type="pvh"
vcpus=4
memory=2048
maxmem=4096
#bootloader="pygrub"
kernel="/usr/local/bin/grub.xen_pvh"
# Enable pv on hvm drivers
xen_platform_pci=1
vif = [ 'mac=00:16:3E:DE:AD:78, bridge=xenbr0' ]
disk = [
'phy:/dev/disk/by-path/ip-10.255.255.2:3260-iscsi-iqn.2005-10.org.freenas.ctl:xen-lun-35,xvda,w'
]
# usb passthrough for the zwave stick
usbctrl=['type=auto,version=2,ports=4']
usbdev=['type=hostdev,hostbus=2,hostaddr=3']
=============
There is a grub.cfg in /boot/grub/grub.cfg on that disk. It's a standard
ubuntu 18.04 vm, which I've built a kernel with the PVUSB drivers on it.
Trying to get that kernel to boot easily, and a more real grub
environment would help solve it.
Thanks!
