Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

Hello, I have a problem shutting down a domU with xen-4.1.2, which doesn''t terminate the corresponding blktap2 process, since one (other) VM uses a image file, which contains spaces in its file name. /var/log/xen/xend-debug.log has the following information: Unhandled exception in thread started by Traceback (most recent call last): File

Hi, In most cases we use image files as virtual disks under the full-virtualization situation.On the version 4.1.2 of xen,I do the following command: ############################################################ dd if=/dev/zero of=myraw.img bs=1M seek=8K count=1 #Before the command below I install the operating system in myraw.img qemu-img-xen create -b myraw.img -f qcow2 myqcow1.img 20000M

Hey! As I''ve already written about two days ago, I''m having major trouble getting blktap2 to work properly. After trying xen-sources-2.6.32-xen-r1 from Gentoo (where Andrew Lyon, the maintainer, has already confirmed that he''s hitting the same problem as me, i.e. the blktap2 driver is dysfunctional in the kernel), I decided to give a pv_ops-Kernel a try, and checked out

Hi, I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 + http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-4.tar.bz2, and one of the things that I noticed immediately is there are two problems with tapdisk and this combination. First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works. When tested with HVM domU, it boots, but there was no disk
