Description Douglas Furlong 2006-12-07 11:52:45 EST
Description of problem: When trying to create a virtual machine using the Xen Virtual Machine Manager, the command fails at the point of hitting "finish" Version-Release number of selected component (if applicable): xen-3.0.3-0.1.rc3 How reproducible: Currently 100% Steps to Reproduce: 1. Go through the process of creating a virtual Machine and hit finish Actual results: The following error is generated. Traceback (most recent call last): File "/usr/lib64/python2.4/site-packages/xen/xend/server/SrvDomainDir.py", line 77, in op_create dominfo = self.xd.domain_create(config) File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 228, in domain_create dominfo = XendDomainInfo.create(config) File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 195, in create vm.initDomain() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 1363, in initDomain raise VmError(str(exn)) VmError: (22, 'Invalid argument') Expected results: Virtual Machine to be created, and installation proceed. Additional info: This is on an AMD 64 Bit System. Installation to a LVM Volume created specifically for the task (preformated as ext3). Installation media specified as NFS, with the relevant locations. Please let me know if any additional info is required.
Comment 1 Douglas Furlong 2006-12-07 11:55:42 EST
The same error message appears to be generated when attempting to create the Virtual Machine as a file on the existing file system, or an unformated LVM Volume.
Comment 2 Daniel Berrange 2006-12-07 12:02:23 EST
The 'Invalid argument' method either means you tried to boot a bare-metal kernel, or a non-PAE enabled kernel. What OS are you trying to install ? Please attach the contents of /root/.virt-manager/virt-manager.log from immediately after you get this message.

Heyah I am trying to install FC6 i386. I've attached the file requested.

Comment 5 Daniel Berrange 2006-12-07 12:49:30 EST
You can't install a 32-bit paravirt guest, on a 64-bit host with Xen - the HyperVisor does not support the mixed arch in paravirt mode. If you want to run mixed architecture like that, you'll need to do a fully-virt / HVM install of the 32-bit guest.

BTW, quick timesaving tip wrt... > Installation to a LVM Volume created specifically for the task (preformated as ext3). There is no need to pre-format the partition in Dom0 - you can simply create the bare logical volume. When anaconda runs in the guest OS installer it will partition the LV, and format it as needed.
Comment 7 Douglas Furlong 2006-12-07 12:52:14 EST
Ahhh, okay. However, the fully-virt option is grayed out, due to lack of support. When I was saying what I was doing, it suddenly dawned on me that it may be a slight issue. Sorry for the wasted time. Though, is it not possible for a more informative error?
Comment 8 Daniel Berrange 2006-12-07 12:54:39 EST
The problem is that XenD currently only gives back 'Invalid argument' when creation fails. We're actively working with upstream Xen developers to get significantly improved error reporting incorporated into XenD, which would let us tell user exactly what went wrong.
