Hi, I try to exchange datas between host and Guest by adding these lines in a guest .xml conf file : <channel type='pty'> <target type='virtio' name='arbitrary.virtio.serial.port.name'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> Then /dev/virtio-ports/arbitrary.virtio.serial.port.name is exposed in the guest and a /dev/pts/x is seen as source path on the host.
I checked that on two Linux hosts : 1) libvirt-daemon-driver-qemu-1.2.8-16.el7_1.3.x86_64 qemu-kvm-1.5.3-86.el7_1.5.x86_64 qemu-kvm-common-1.5.3-86.el7_1.5.x86_64 qemu-guest-agent-2.1.0-4.el7.x86_64 ipxe-roms-qemu-20130517-6.gitc4bce43.el7.noarch qemu-img-1.5.3-86.el7_1.5.x86_64 Linux sparring 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux 2) qemu-img-0.12.1.2-2.415.el6.x86_64 qemu-kvm-0.12.1.2-2.415.el6.x86_64 gpxe-roms-qemu-0.9.7-6.10.el6.noarch Linux orion 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux The device is only exposed on the guest of the first host . Is it due to a too old version of qemu and/or Linux on the second host or some packages missing on this second host ? Thx. Regards,
