A colleague of mine asked this question on xen-users, but it may be more of a developer question. We need to make multiple independent console connections to a paravirtualized VM (not 2 windows sharing a single console), and without using the network (no telnet or ssh solutions). Searching the archives I've found about 6 threads discussing this, among them: This one, which says it was on the roadmap for versions 2 and/or 3: http://lists.xensource.com/archives/html/xen-devel/2006-07/msg00424.html > Currently, each PV guest is allowed just a single virtual serial > console device. Although once we have PV framebuffer support (and > associated virtual terminals) virtual serial console support will be > less important, it would still be nice to support multiple consoles > per guest. This should be relatively straight forward, requiring > updates to the console frontend driver, xenconsoled, and the tools. > ... > 2/3 & linux & support for multiple virtual serial consoles And these, opening the possibility of 2 consoles (on the paravirt framebuffer and on a virtual serial port): http://lists.xensource.com/archives/html/xen-devel/2006-08/msg00170.html http://lists.xensource.com/archives/html/xen-devel/2006-09/msg00072.html Can anyone tell me if and when it will be possible to get 2 independent consoles into a paravirtualized guest? Or will the kernel always have only one input/output stream, resulting in behavior similar to the "multiple windows to a shared console" scenario we have now?
