Spice opens many FDs to handle different channels (display, usb, sound, etc.). For remote SSH URIs, this means we launch multiple SSH proceses. We do so by forking off the process, and when SSH has successfully authenticated, the data starts flowing. If using spice + remote SSH w/o SSH keys, you need to put your data into ssh askpass. askpass wants to own the display for security reasons. When all the channel requests start coming in, we were launching multiple ssh processes one after another. This upset askpass and generally caused havoc in the app. Add some infrastructure to serialize launching ssh processes. We only launch the next ssh process if spice/vnc have conclusively connected or errored out the connection. This makes connection a bit slower for the non-askpass ssh case (about 1.5 seconds), but will ignore avoid this oft reported problem.
Virtual Machine Manager ======================= This application provides a graphical tool for managing virtual machines via the libvirt library. The front end of the application uses the GTK / Glade libraries for all user interaction components. The back end uses libvirt for managing Qemu/KVM and Xen virtual machines, as well as LXC containers. The UI is primarily tested with KVM, but is intended to be reasonably portable to any virtualization backend libvirt supports. Pre-requisite software ====================== virt-manager was ported to GTK3 at the beginning of 2013. Older GTK3 or pygobject3 versions likely will not work for running virt-manager. Earliest tested versions of major components: python >= 2.6 gtk3 >= 3.6 libvirt-python >= 0.4.0 pygobject3 >= 3.4 A more detailed dependency list can be found in virt-manager.spec.in.
