    The warning indicates you are using the older xm toolkit instead of the newer xl toolkit. You can ignore that one for now. Looks like you are trying to allocate more memory than you have available in hardware. How much memory is in the host machine? How much is allocated for Dom0? Russ...

    The hypercall docs can be found here: http://wiki.xenproject.org/wiki/Hypercall Since you are down in the weeds of the system, I'd suggest asking any follow-up questions in the xen-devel mailing list. The developers hang out there and you will likely need developer assistance if you have any issues. Learn more about xen-devel ...

    This appears to be more of an Ubuntu question more than a Xen Project one. FWIW, I found this on the web: http://ubuntuforums.org/archive/index.php/t-2098490.html It appears to be a moderately common problem which is not Xen Project specific. If you are set up using grub, check the grub config file (possibly in /boot/grub/grub.cfg) to s...

    Great to hear you're up and running! I don't know if there is a set rule for the disk names, but it makes sense to follow the Linux convention that the first drive in the "hd" chain is "a", followed by "b", and so forth. I believe the boot sector needs to be on hda by default (unless you explicitly override), but I'm not sure there is a requirem...

    What version of Xen are you using? Based on the "xm is deprecated" warning, it should be somewhere between 4.1 and 4.4, but the version could be significant. I'm not sure what to make of this one exactly. Try removing the "device_model = 'qemu-dm'" syntax and substitute "device_model_version = 'qemu-xen-traditional'" instead (note the change...

    This is not something I've done, but I know of no reason why it couldn't be done. As a type 1 hypervisor, Xen Project software is the platform for all sorts of small network devices which populate guest VMs using unikernels. NEC's ClickOS comes to mind here (http://cnp.neclab.eu/clickos/). I came across an old post from someone doing somet...

    John, Xen Project and XenServer are two different animals. XenServer is, in essence, a distribution of the Xen Project Hypervisor with other software added, a nice installation procedure, etc. Your question has to do with the particulars of how XenServer sets up networks, so you'd do best with a XenServer-specific support channel. I...

    I've seen some older posts on the web about this, but none seem particularly clear about the core of the problem. Interestingly, it looks like you may have to make sure that Windows itself can properly use a 4K size: http://support2.microsoft.com/kb/982018 I think you'll need to take this issue to the XenServer folks. For the ...

    Ryan, I won't put words into Tim's mouth, but I'd classify XenServer as a distribution of Xen Project software, in the sense that Ubuntu is a distribution of Linux. XenServer bundles the Xen Project hypervisor along with a customized Domain 0, some extra software (like XenCenter), and a simple installation experience. XenServer wraps all t...
