[Xen-devel] Intel Z270 support
I have two ASUS PRIME Z270-A machines based on Intel Z270 chipset and am wondering about when support will be available for them and what I can do to speed this up. But I have not done anything to do with kernel work since years ago when I read a lot of the main parts of the Linux 2.4 Kernel. Also I did code to get into and out of protected mode before this. Heres the datasheets that cover the chipset :- https://www.intel.com/content/www/us/en/chipsets/200-series-chipset-pch-datasheet-vol-1.html https://www.intel.com/content/www/us/en/chipsets/200-series-chipset-pch-datasheet-vol-2.html Regards, Aaron -- Aaron Gray Independent Open Source Software Engineer, Computer Language Researcher, Information Theorist, and amateur computer scientist. ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

I tried installing Xen 4.9 provided with Fedora 28 but it did not work. Can I get support with this please ?

Before it was actually booting past the [U]EFI stage. And I am not sure why it is faultering oon this. I have turned off UEFI on the Motherboard. Loading Xen 4.10.2.config ... error: file `EFI/fedora/x86_64-efi/module.mod' not found. error: file `EFI/fedora/x86_64-efi/multiboot.mod' not found. error: can't find command `multiboot'.

I have managed to install, boot, and run F28 in KVM'ed F28 so my hardware is supported properly by KVM.

F29 Beta has 4.11.0 At present I have one instillation on F29 that worked straight away with :- sudo yum groupinstall 'Virtualization' sudo yum install xen And another were I did a yum update first and Xen it does not function with the missing module.mod and multiboot.mod issue that was found in F27 and F28. https://bugzilla.redhat.com/show_bug.cgi?id=1486002#c36 I just need to do the diff's on /boot and the rpm's tomorrow to see what if I can find the issue.
