Hi Daniel,
Thanks for your comments.
So far there's no device in QEMU to align with chardev on FSL PowerPC platforms like
spapr-pty for IBM PSeries.
Maybe it needs patches to QEMU. I'll take deeper investigation on it.
That's really a QEMU issue then - every chardev needs to have a
corresponding -device to associtte with.
But can't get any output when connecting domain with a simple
private root filesystem.
# vi vm2.xml
<domain type='lxc'>
<name>vm2</name>
<memory>25536</memory>
<os>
<type>exe</type>
<init>/sbin/init</init>
</os>
<vcpu>1</vcpu>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>destroy</on_crash>
<devices>
<emulator>/usr/libexec/libvirt_lxc</emulator>
<filesystem type='mount'>
<source dir='/media/ram/vm1-root'/>
<target dir='/var/lib/libvirt/lxc/rootfs'/>
</filesystem>
<interface type='network'>
<source network='default'/>
</interface>
<console type='pty' />
</devices>
</domain>
# virsh -c lxc:/// define vm2.xml
# virsh -c lxc:/// start vm2
Domain vm2 started
# virsh -c lxc:/// console vm2
Connected to domain vm2
Escape character is ^]
Do you have any suggestion?
Most likely is that the OS you are running has not decided to run
any login process on the console
'/sbin/init' itself does not directly provide any console interaction
It needs to be configured to run a mingetty process or similar
