In a XenServer environment to get some point to the ugly bug that you can install any Linux distros directly from the Web. This äusert as follows:

Error: The bootloader for this VM returned an error – did the VM installation succeed? Error from bootloader: Return code:1 ; Log = INVALID_SOURCE. Unable to access a required file in the specified repository: http://….

XenServer – Import a virtual machine to the Console

xenserver55Recently I have on the Export the virtual machine written to the XEN console. Now there is a little guide as I exported this machine at the console again import.

First, we will contact you via SSH with root at the right XenServer. Since our *. XVa is on a Windows File Share this first we connect with the command:

[root@XENS001 /]# mount -t cifs “//fileservername/XenServer” -o username=domain/admin,password=123456 /backup

To test the connection, we can list the content in this directory:

[root@XENS001 /]# ls –an /backup

Now we start the actual import of the machine:

[root@XENS001 /]# xe vm-import filename = / backup / DebianEtch.xva preserve = true

After the successful import is displayed on the console, the generated uuid and the machine is shown in the XenServer Console. Now, all settings such as eg. Network, CPU, Pool Server examined and possibly. be corrected.

HowTo: XenServer – Backup of virtual machines to the Console

First, we need a network share where we can store our backups. For many this is a shared folder on a Windows host, the simplest solution be, but it is also with NFS shares.

If we have created a share on a Windows Server (Rights note), we have yet to map this share with the XenServer Console. To this end, we are connecting with SSH to our XenServer (xsconsole or with the) and we create a new directory, the release of the Windows to represent the XenServer.

[root@xenserver /]# mkdir /backup

Then we mount our Windows release with the following command:

HowTo: Xen Server – Free hard disk space – Snapshots

In the current version XenServer 5.5 SP2 comes before it is unfortunately still not deleting snapshots created the required disk space is freed.

This point does the point of hurt, of course,, as for a virtual machine with a hard disk of eg. 50 GB in a Snapshot (the just consumed only a few MB) additional 50GB of storage to be reserved. Deleting this will not receive. That would still not the problem if we would see this in the Overview of Storage. This is not the case.

Now Citrix has already SP1 XenServer 5.5 a small program built from exactly these hard drives from deleted snapshots. This is the Console application:

coalesce-leaf

The following steps are necessary:

  • Backup of virtual machine (protects against data loss)
  • In XenCenter in the affected virtual machine under the "General" to pick out the UUID
  • on the console (Xenserver) following command to give: coalesce-leaf –u <uuid of VM>

PLEASE NOTE: The affected machine is required for the process be able to perform the operations.
