...uest, I have followed the direction( link<http://pastebin.com/f6a5022bf>) in Xen-Users Common Questions Guide. It says the first step is "install kernel-xen with correct initrd" After "yum install kernel-xen" was executed, following errors were showed: WARNING: No module xen_vbd found for kernel 2.6.18-164.15.1.el5xen, continuing anyway grubby fatal error: unable to find a suitable template Even if yum result showed that installation is completed, xen-kernel was not added to /boot/grub.conf. the reason I want to convert hvm to pvm is that we want to use our lagacy syste...

hello, I know this not quite a xen problem but im sure a fair number of people are using debian for their dom0 and maybe have some insight into this. I have a large number of dom0''s running squeeze and for a long time i was hoping for pvhvm to make into the official debian xen packages and recently during some periodic updates I noticed pvhvm working after a kernel package update. Now

Dear list, This is the V4 of the trim support for xen-blkfront/blkback, Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all "trim" stuffs in the patches, and use "discard" instead. Also we updated the helpers of blkif_x86_{32|64}_request or we will meet problems using a non-native protocol. And this patch has been tested with both SSD and raw file, with SSD we will
