SELinux error when trying to create virtual machine
Last modified: 2008-01-10 23:08:51 EST
Description of problem: virt-manager 0.4.0, Fedora 7 Test 4, Xen kernel 'Creating a new virtual system' System Name: openSUSE (10.3 Alpha 3 DVD in drive) Fully Virtualized CD-ROM or DVD: SU103Alp.001 (DVD-ROM image name) OS Type: Linux OS Variant: Generic 2.6.x kernel Simple File: /var/lib/xen/images/openSUSE 10 GB, entirely allocated Shared physical device, xenbr0 512 Max Memory, 512 Startup Memory (2.00 GB in host) 1 VCPU After I click 'Finish', I get: 'Unable to complete install: 'virDomainCreateLinux() failed POST operation failed: (xend.err 'Device 0 (vif) could not be connected. Hotplug scripts not working.')' See attached PNG. Version-Release number of selected component (if applicable): 0.4.0

I reinstalled with default kerrnel, and set SELinux to 'Permissive.' Still got the same error, so it looks like it's not SELinux related. I assumed it was SELinux related because of all the SELinux alerts I was getting.
I have also had this problem installing F7. I have also tried both ethernet options in the virt-manager. Host:Fedora (2.6.20-2925.11.fc7xen) Guest URL : http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Fedora/i386/os/ Install Location: /var/lib/xen/images/ Virtual Network : Default (Though I have had the same problem using Shared Physical Device : eth0) VM Max = VM Startup = 256MB VPU = 1
I have been able to get past this there are a couple of threads that talk about this particular problem please refer to them for further details. I eventually installed sysfsutils (http://lists.xensource.com/archives/html/xen-users/2005-11/msg00127.html) This did not seem to work however it might be required anyway. what did work was doing steps 2 and 4 of this post (http://lists.xensource.com/archives/html/xen-users/2005-10/msg00152.html) 2. /etc/xen/scripts/network start 4 /etc/xen/scripts/vif-bridge up domain=RHL vif=vif1.0 bridge=xen-br0
Further to the above. The previous efforts allowed the completion of the image creation but when it came to installing the client OS the system failed as it could not initialise the ipv6 ethernet stack. It didn't matter which ipv6 option you chose or even if you turned it off in the install options. After trawling through the logs on the host OS the new errors reported were xen-hotplug.log mkdir: cannot create directory `/var/run/xen-hotplug': Permission denied Given that I had problems reported by the selinux trouble shooter in creating this log file I assumed that there is a problem with the selinux permissions for virtulization and so set selinux to to disable and then ran 'fixfiles relabel'. After starting the entire process again I was able to complete the intallation. To me this is defiantly an issue with selinux not allowing the correct establishment of the networking scripts.

If you are still encountering problems with this could you provide /root/.virt-manager/virt-manager.log From just after an attempt to create a VM, along with the output of 'ifconfig -a', 'brctl show' and /var/log/xen/xend.log
