[Xen-devel] bad page flags booting 32bit dom0 on 64bit hypervisor using dom0_mem (kernel >=4.2)

I recently tried to boot 32bit dom0 on 64bit Xen host which I configured to run with a limited, fix amount of memory for dom0. It seems that somewhere between kernel versions 3.19 and 4.2 (sorry that is still a wide range) the Linux kernel would report bad page flags for a range of pages (which

Hi, while playing around with xen-4.6 I stumbled over an odd problem and am wondering whether anybody has seen the same. A method to relatively quickly reproduce this for me seems to: - Start one domU (PV or HVM does not seem to matter) - Repeatedly call xenstore-ls a few times I think I never

[Xen-devel] Fwd: Xen-4.1.6.1 backport for XSA156

Hi Jan, hi Andrew, I am currently trying to backport the changes of XSA156 back to Xen-4.1.x and I am struggling with the VMX side. I did see the backports made for 4.2 and 3.4 on the security mailing list but I am not sure the 3.4 backport is not having the same issues (or similar ones).

[Xen-devel] Using kexec-crashdump with recent Xen and Linux HVM

After being asked about this I started to play around with Xen-4.4.1/4.5 together with HVM Linux guest running 3.13/3.16/3.19. With mixed success. Usually rather failing. From a bit of research most activity to enable things were back in 2011. There was a bit of a throwback around Linux 3.2[1]

While experimenting/testing various kernel versions I discovered that trying to boot a Haswell based hosts will always crash when booting as Xen dom0 (Xen-4.4.1). The same crash happens since v3.19-rc1 and still does happen with v3.19-rc7. A bare metal boot is having no issues and also an Opteron
