...tuff and a grub.cfg on the domU filesystem. If that works, then it's a matter of figuring out how to get that grub-i386-xen_pvh.bin and the modules built in the packaging? Thanks, Hans [0] Background of the whole story how we ended up doing so for PV: https://tech.mendix.com/linux/2014/09/06/pvgrub2/ https://tech.mendix.com/linux/2014/09/16/pvgrub2-live/

Hi, Having a problem getting a domu to boot correctly. When I enter xl create guest it boots straight into grubdom. If I enter the config location in grubdom t boots as expected. The location of the grub.cfg is the same in my domu config as what in entering but just will not work. Any ideas? Ian .

There is some interest lately in making a self-contained grub2 boot image - call it pvgrub2, used for booting paravirtual domU in xen where a grub2 config is installed. First attempt------------------ I first tried using the grub2*.src.rpm from the C7 vault. I configured as shown belowhttps://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/ for headers, I use...

Hi Debian Grub maintainer, In december, Xen PVH support has been committed in grub master: https://www.mail-archive.com/grub-devel at gnu.org/msg28125.html The last pieces needed in the Linux kernel to boot PVH with grub2 landed in Linux 4.20. I asked our kernel team to carry those patches on top of the Linux 4.19 kernel that is going to ship in Buster, and that wish was granted:

...grub 1 support is raising. Tody I received a notification from Arch Linux who are also doing this. The problem with this situation is when a distro installs grub2 because of a package dependency. So what I would like to know is whether there are more alternatives for PV than pvgrub. ExtLinux or pvgrub2 would be nice.. Mark

Package: xen-utils-4.4 Version: 4.4.0-1 Tags: patch grub-xen-host implements the dom0 side of the x86 pv bootloader protocol[0] and is now in unstable. This enables the use of pvgrub2 in preference to the less secure pygrub. The following patch makes the (trivial) change. Once I have a bug number I will add the Closes: and push to a feature/bugNNNN branch. Ian.

Xen upstream BoF ================ We had a discussion around Xen and packaging at Debian's annual developer conference (Debconf) a few weeks back: https://summit.debconf.org/debconf15/meeting/279/xen-upstream-bof/ These are my notes, I think there is probably stuff of interest to most distro people, not just Debian folks. The session was scheduled in a small, out of the way, room. Around 2

This patch set should make it easier to maintain PV-GRUB2 installations. The general idea is based on discussions I had with Xen developers (mainly Ian Jackson) at the Ubuntu Developer Summit in May 2011; though I never did manage to get the core port done and Vladimir beat me to that, I think the configuration approach we discussed there is still valid and useful. The idea here is that people
