Event channels are like PV interrupts and in conjuction with grant frames form a data transfer mechanism for PV drivers. They are also used for inter-processor interrupts. Guests with a large number of vcpus and/or many PV devices many need to increase the maximum default value of 1023. For this reason the native Xen config format supports the 'max_event_channels' setting. See xl.cfg(5) man page for more details. Similar to the existing maxGrantFrames option, add a new xenbus controller option 'maxEventChannels', allowing to adjust the maximum value via libvirt.
