Hi,
Any news?
In the meanwhile, from the qemu command above, I've noted that it
tries to boot from HD.
In fact, the conversion from Xen config file to XML missed to add a
<boot> element for cdrom (instead, it wrongly added a duplicate
element for HD).
So, I've tried to add this <boot> element, thus resulting in:
<os>
<type arch='x86_64' machine='xenfv'>hvm</type>
<loader>/usr/lib/xen/boot/hvmloader</loader>
<boot dev='hd'/>
<!--
<boot dev='hd'/>
-->
<boot dev='cdrom'/>
</os>
Now, the QEMU command spawn by virsh is
/usr/lib/xen/bin/qemu-dm -d 3 -domain-name testvm -vnc 127.0.0.1:0
-videoram 8 -boot cd -vcpu_avail 0x01 -net none -M xenfv
Now, vncviewer is able to connect, I can see the CentOS initial menu,
but when I choose to start the installation the vnc window becomes
black and I can do nothing.
I've tried to start the installation in several ways, including the
basic graphics mode (VESA) or by adding the "text" parameter to the
kernel boot options.
But the result is the same.
