...rade to unstable and use the 3.4 deb packages. My problem is that there isn''t a kernel package so when booting you cant boot into xenified kernel mode. If i try and use a kernel from the stable tree it messes things up. How is everyone else running the 3.4 packages? Ive read about pv_ops but i don''t know how to install or use it. Any ideas?

Hi, i''ve new hardware for my XEN server. It boots pv_ops kernel now. But with my pv_ops kernel the server doesn''t power off. Even there isn''t this messages for it. When i boot a 2.6.24 from Ubuntu it power off. Regards, Stefan Kuhne _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com...

Hi, I have several servers Supermicro - running Xen 3.4.1 @ debian 5.0 x64 running without any issues for more than year. Now I bought new server with exactly same config and installed Ubuntu 10.04 x64 - Xen 4.0.1-rc4 - 2.6.32.16 pv_ops - base Ubuntu 10.04 install boot without issues - Xen 4.0.1-rc4 compiled and installed withou any problems - 2.6.32.16 pv_ops dom0 kernel with custom config. That config has Boris verified as working here in mailing list. Also me mysel booted this kernel config correctly in vmware machine with m...

I'm looking at adding Xen SMP support, so I'm trying to work out what pv_ops we need, and how to cut into the existing smp stuff. smpboot.c has a mixture of stuff which is generally useful for SMP stuff (the various CPU sets, and presumably the sibling relationships are useful in principle), but also a whole pile of APIC stuff which is irrelevent to Xen. It has these e...

This series removes some no longer needed stuff from paravirt infrastructure and puts large quantities of paravirt ops under a new config option PARAVIRT_XXL which is selected by XEN_PV only. A pvops kernel without XEN_PV being configured is about 2.5% smaller with this series applied. tip commit 5800dc5c19f34e6e03b5adab1282535cb102fafd ("x86/paravirt: Fix spectre-v2 mitigations for

When I try to virt-install a PV instance of F11, I''m getting an ''invalid kernel'' message, as if it''s not a Xen kernel. I have tried both the i386 and x86_64 versions. Is there any weirdness with this distro that I''m not aware of?

Hello, I seem to be having some troubles regarding the latest 2.6.31.6 and 2.6.32.9 Xen dom0 pv_ops trees. Our platform: -Xen 3.4.3-rc3 (also tried 3.4.2 on 2.6.31.6 pv_ops dom0) -2.6.32.9 pv_ops dom0 kernel, perhaps a week old checkout from xen/stable git (can provide changeset if requested). -100+ domU''s, all PV. Ever since we switched to a pv_ops dom0 kernel (we were using 2.6.26...

The last 4 patches of this series require my Xen cleanup series https://lore.kernel.org/lkml/20180717120113.12756-1-jgross at suse.com/ which hides more Xen PV-only code behind CONFIG_XEN_PV. Changes in V2: - patch 4: shorten pv_ops sub-structure names (Jan Beulich) - patch 11: new patch Juergen Gross (11): x86/paravirt: make paravirt_patch_call() and paravirt_patch_jmp() static x86/paravirt: remove clobbers parameter from paravirt patch functions x86/paravirt: remove clobbers from struct paravirt_patch_site x86/p...

Hi all, I've been looking at the next steps to try to get Xen running fully on top of pv_ops. To that end, I've (just) started looking at one of the next major jobs --- i686 dom0 on pv_ops. There are still a number of things needing done to reach parity with xen-unstable: x86_64 xen on pv_ops Paravirt framebuffer/keyboard CPU hotplug Balloon kexec driver domains but it...
