Managing guests using virt-manager

As a GUI interface, virt-manager is relatively self-explanatory to use.

By default virt-manager will only connect to the user's guests on the local server.

To connect to the system hypervisor on a remote server you need to add the server using the File/Add Connection tab, with settings similar to the following :-


Adding an ISO image

virt-manager makes it fairly easy to add an ISO image file to a VM - that is, put a virtual CD in the virtual CD drive - so that the VM can for example boot from the CD. Once virt-manager has connected to the remote server (see above), connect to the required VM, click "Details" then select "ISO CDROM 1". Give a value for "Source path" which describes where on the KVM server you have put the ISO image. (Then remember to copy the iso image to that location!) ISO files should be put on the KVM server's local filesystem, rather than on a network filesystem such as AFS.

"Error refreshing hardware page"

(August 2016) If virt-manager pops up an "Error refreshing hardware page" it may be because you're running it on SL7, managing a guest which is hosted on an SL6 machine. The error should go away if you quit virt-manager, ssh to the SL6 KVM server, and run virt-manager there instead. The virt-manager version on SL7 is quite a bit ahead of that on SL6 and some incompatibility seems to have crept in between the two.
