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

Do you know if squeeze has xen support? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Establishes correct cleanup behavior for blktap devices. This patch implements the release of the backend device before calling for the destruction of the userspace component of the blktap device. Without

For those wanting to know how to mount filesystems through blktap2 here is how you do it, as I couldn''t find it fully documented. The instructions on the blktap2 readme file are rather out of date. You can mount them under Dom0 like so. e.g. to mount a vhd file, sudo xm block-attach 0 tap2:vhd:/home/xen/xenwin7-persist.vhd xvdb w 0 Now the device should appear under /dev ls

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

Hi, When I do the "make install-tools" with xen-4.2-unstable, there are some errors about "warn_unused_result". Is it the error in code or the error in the compiling environment?

Hi, I''m currently trying xen 4.1.1 with the 3.0.0-rc5 (heard that it now contains the xen code to run as front or back xen domain). Everything seems to run fine, except that I am trying since a few hours to mount a .vhd file in the dom0. What I tried so far: to create a blank vhd file (this is working): host# vhd-util create -n /storage/test.vhd -s 20G Then i try to mount the 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

We have a great many VMs that are stuck on Lenny because of this. Probably can build it ourselves, but would prefer to avoid the maintenance nightmare. Please make this happen, as we really like Debian.

Hi, I explain what I want to do.. All the operators share their phones. The number of the operator isn't constant, so it's possible that two operators share all the phones. They need to move all around, so they pick up the first phone they find. If there are only few operator is very annoying for them to ear the other phones ringing while they are at the phone! So I'dd like to limit
