Since qemu v1.1.0 upstream commit 8cf364, qemu implemented shared-flag handling the default qemu vnc server behavior from mode 'ignore' to 'allow-exclusive'. The direct effect is as follows for libvirt user: vncviwer client: before: all client could share desktop without any option after: all client need -Shared options for desktop sharing. One client without -Shared option breaks others's connection virt-viewer: before: virt-viewer could support multiple desktop sharing after: only one active connection
If we need to keep the original vnc behavior at libvirt level, the '-vnc :1,share=ignore' need to add into qemu commandline.
Any ideas about this?
It sounds like we need an XML attribute, with several states (exclusive, allow-share, force-share, ignore), and then specify that omitting the attribute allows the hypervisor to pick its own default. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
