I''m trying to compile pvscsi out-of-tree, and I''m getting an error that set_phys_to_machine is not defined when I try to load the module (with the warning to that effect at compile time too). This used to work fine in pvops. It seems that netfront uses that symbol in a module so I''m confused as to why pvscsi can''t... any suggestions? Is it one of the virtues of netfron...

Hello, does anyone knows, if and when pvscsi will be available in the official linux kernel? Kind regards. Christian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This series implements ballooning for Xen on ARM and builds and Mukesh''s PVH privcmd stuff to implement foreign page mapping on ARM, replacing the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch. The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch

Hi linux/ia64 developers. Few days before Eddie posted the mail for Linux/IA64 paravirtualization. But only a few responded partially because there was no reviewable patches. Here is the patches for xen/ia64 Linux paravirtualization. The goal is to merge IA64 xen Linux paravirtualization for both domU and dom0 eventually. However the first step is to merge domU portion. As you can see from the

Hi Jeremy. Here are the 3 patches for ia64/xen support. The first one is just to move manage.c under drivers/xen. This is trivial. The second and third ones are for compilation fix on ia64. You may want to postpone those 2 patches to make your merge task easy as you said before. thanks, Diffstat arch/x86/xen/Makefile | 2 +- drivers/xen/Makefile | 2 +-

Hi, Here is the third version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head.

Hi everyone, I am very excited to see that dom0 pvops is finally coming close to working, so I wanted to give it a try. >From the description it was not clear to me which kernel to chose as base for the patches.hg, so I took the latest (that was ~ 2 weeks ago) kernel on git.kernel.org I could find (post-2.6.28 git tip at that point). I managed to more or less apply all of the patches in the

We have implemented hugepage support for guests in following manner In our implementation we added a parameter hugepage_num which is specified in the config file of the DomU. It is the number of hugepages that the guest is guaranteed to receive whenever the kernel asks for hugepage by using its boot time parameter or reserving after booting (eg. Using echo XX > /proc/sys/vm/nr_hugepages).
