[Xen-devel] Summary of Xen/pv_ops changes/additions in upcoming Linux 2.6.28?
Hello list! http://wiki.xensource.com/xenwiki/XenParavirtOps I changed that wiki pv_ops page to have the list of features added in Linux 2.6.27. I could also add to the wiki pv_ops page the stuff that''s queued for Linux 2.6.28. Does someone have a list/summary about that? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

While I wouldn''t put it in production just yet, for normal desktop/developer workloads it has proven to be pretty stable. Is this statement still well founded? -- Cheers, Feri. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

That also works OK. I use the 686-bigmem flavour only, but others successully run the 64 bit version AFAIK. -- Feri. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

That also works OK. I use the > 686-bigmem flavour only, but others successully run the 64 bit version > AFAIK.Unfortunately There''s no 64 bit version of the domU pvops kernel in Lenny. 64 bit domU first appeared in 2.6.27, I think, and the backport was too involved for me to consider. What Lenny will have is a kernel with the SUSE forward ported non-pvops patch for 32+64 dom0 and 64 domU support (the -{686,amd64}-xen packages), in addition to the -686-bigmem pvops kernel for 32 bit domU.
