Re: [libvirt] Libvirt Support Virtio-serail

Thanks for the input Actually I wanted to have private communication channel b/w host and guest By default I cannot have multiple console on guest through virsh console guestname ( they all are dependent on each other , if I execute a command on one shell its output is reflected on all of them ). I wanted to login into guest from multiple shells(and the console should be independent of each other) Virtio-serial have this feature ,I have gone through various install option on web , but they don't seem to work. Our kernel version for host and guest is 2.6.32-220.4.1.el6.x86_64 We goes through the mentioned link And edit our xml file by adding <channel type='pty'> <target type='virtio' name='arbitrary.virtio.serial.port.name'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> Then we tried to access the channel device through virsh console guest_name dev_name It gives error :- # virsh console serial vport0p1 Connected to domain serial Escape character is ^] error: internal error cannot find character device vport0p1 but the vport #ls -l /dev/virtio-ports/arbitrary.virtio.serial.port.name lrwxrwxrwx. 1 root root 11 May 14 05:01 /dev/virtio-ports/arbitrary.virtio.serial.port.name -> ../vport0p1 Regards Pankaj Rawat -----Original Message----- From: Christophe Fergeau [mailto:cfergeau@redhat.com] Sent: Monday, May 14, 2012 1:55 PM To: Pankaj Rawat Cc: libvir-list(a)redhat.com Subject: Re: [libvirt] Libvirt Support Virtio-serail Hi Pankaj, On Mon, May 14, 2012 at 03:52:54AM +0000, Pankaj Rawat wrote: I think http://libvirt.org/formatdomain.html#elementCharChannel is what you are looking for, if it's not, please describe in more details what setup you want to achieve.
