You can try to make the current virtio-serial backend in Qemu work on Xen, that shouldn't be difficult, but it would only work with HVM guests. Otherwise you can try to use a Xen PV serial for your purposes: multiple PV serials don't work out of the box, but I have tested them a little while ago and they do work fine. You need to hack xl to create multiple PV serials frontend/backend pairs (see init_console_info in tools/libxl/xl_cmdimpl.c), then you need these two patches in the guest kernel (unfortunately they are not yet upstream): - hvc_xen: support PV on HVM consoles e76b17aae62d13cebd4cc33415b4f0cc72316345 - hvc_xen: implement multiconsole support d6edaed101e089b80257bcbb3141308a97ea489e look at this branch: git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git 2.6.36-rc6-pvhvm-v8 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
