FWIW dom0=pvh is a xen command line option. It is new/experimental.
The point is I never to get a pinging dom0. So not succeeding at all.
All that is seen is a blank screen after the hyper-visor hands off to
the kernel. A stripped down example set of grub looks like below. Note
no quiet or rhgb options.
kernel /xen.gz dom0_mem=2048M iommu=required,debug,verbose dom0=pvh
module /vmlinuz-4.18.0-2.el6xen.x86_64 ro root=<sniped> pcie_aspm=off
panic=30
module /initrd-4.18.0-2.el6xen.x86_64.img
So my question, restated, are there any gotchas in getting dom0 booting
specifically in pvh mode?
