AW: Exporting Dom0 disks to DomU as SCSI disks doesnot work
Hello Digvijoy,
> Does your kernel have inbuilt support for Logical Volumes

Multi-device support is compiled into my DomU kernel, device-mapper is
built as a module.
But I don''t think this has something to do with my problem because

XEN 3.1: critical bug: vif init failure after creating 15-17 VMs (XENBUS: Timeout connecting to device: device/vif)
We have found a critical problem with the XEN 3.1 release (for those who are running 15-20 VMs on a single server). We are using the official XEN 3.1 release on a rackable server (Dual-Core AMD Opteron, 8GB RAM).
The problem we are seeing is that intermittently vifs fail to work properly in VMs after we create around 15-17 VMs on our server (all running at the same time, created one by

How HVM domain distingush ioemu disk and VBD disk
...qemu-dm will recognize disk had, hdb, hdc, hdd, and VBD drive can recognize all disk (had~hdd, hde, hdf ...) . So the result is: qemu-dm will mount /dev/hda-hdd, and VBD driver will mount the rest (/dev/hde,...). Actually, VBD will also try to mount /dev/hda..., but failed with error message "register_blkdev: cannot get major 3 for ide", since the /hda is already mounted as qemu-dm disk.
This looks a litt bit confusing. So I just wonder: is this the expected behavor? Do we intend having some explicit mechanism to indentify ioemu disk and VBD disk?
Best Regards
Ke

linux-3.4-rc0 XENBUS: Device with no driver: device/vbd/51713
Hi Konrad,
I just tried linux-3.4-rc0 (linus his tree, last commit f52b69f86e27903d6896ed5fa7cd280fec8de532) with 3 additional branches from your tree pulled on top of that:
branch stable/for-ingo-3.4.v2 (required for dom0 to boot)
branch stable/for-jens-3.4
branch stable/for-jens-3.4-bugfixes
Hypervisor is xen-4.1.3-rc1-pre
linux 3.3 vanilla works fine
Booting dom0 goes fine, but

suse 11.2 domU on lvm: anyone succeded?
Hi all
I upgraded my testserver from opensuse 11.1 to 11.2 using zypper based method. All updates went smooth as far as there were no errors during the update process. Rebooting the whole farm the troubles started:
not one domU bootet sucessfully, all of them showed the following messages:
...
register_blkdev: cannot get major 8 for sd
...
Volume group "VGsys" not found
before they finally fail
So I though, I set up a new domU using dirinstall, but this script fails also, actually dirinstall_finish fails. Ok, we still got vm-install, but that fails too. So I set up a basic image using suse s...
