Hello everyone,
we have a system (Sun Fire V40z) here were we can only do Para-Virtualisation using Xen because the CPU does not have Virtualization Support. With CentOS 6.6 everythink worked fine. We decided to reinstall the system with Fedora Server 22 because we needed some more up to date packages.
Now we are stuck with Xen. If we try to create a guest using Virt-Manager we get this error:
Unable to complete install: 'cannot fill file '/var/lib/xen/virtinst-vmlinuz.WtErnB': Invalid argument'
Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1855, in do_install guest.start_install(meter=meter) File "/usr/share/virt-manager/virtinst/guest.py", line 386, in start_install self._prepare_install(meter, dry) File "/usr/share/virt-manager/virtinst/guest.py", line 279, in _prepare_install self.installer.prepare(self, meter) File "/usr/share/virt-manager/virtinst/installer.py", line 200, in prepare self._prepare(guest, meter) File "/usr/share/virt-manager/virtinst/distroinstaller.py", line 461, in _prepare self._prepare_kernel_url(guest, fetcher) File "/usr/share/virt-manager/virtinst/distroinstaller.py", line 382, in _prepare_kernel_url fetcher.meter, kernel, initrd) File "/usr/share/virt-manager/virtinst/distroinstaller.py", line 290, in _upload_media kvol = _upload_file(conn, meter, pool, kernel) File "/usr/share/virt-manager/virtinst/distroinstaller.py", line 124, in _upload_file disk.setup(meter=meter) File "/usr/share/virt-manager/virtinst/devicedisk.py", line 812, in setup volobj = self._storage_creator.create(meter) File "/usr/share/virt-manager/virtinst/diskbackend.py", line 352, in create return self._vol_install.install(meter=progresscb) File "/usr/share/virt-manager/virtinst/storage.py", line 733, in install vol = self.pool.createXML(xml, createflags) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3164, in createXML if ret is None:raise libvirtError('virStorageVolCreateXML() failed', pool=self) libvirtError: cannot fill file '/var/lib/xen/virtinst-vmlinuz.WtErnB': Invalid argument
Does anyone have an idea what is causing this and how to solve the problem?
Thanks.
Best regards

That looks like it isn't extracting the kernel from your VM partition or image. It might be being blocked by selinux if you are in enforcing mode, so try setenforce 0 first to switch to permissive mode ( setenforce 1 will get you back to enforcing afterwards).

unfortunately that was the first thing we tried. No change.

You can try running run pygrub directly to narrow down where the problem is, eg.
pygrub --output-directory=/var/lib/xen /path/to/your/vm
If this works you should get a menu and it should download the kernel and initrd of the option you select to /var/lib/xen .
