主题: how to boot from multiple xen version?
I've installed xen4.4 on ubuntu1404 with aptitude. Recently, in order to test the Xen4.6, I manually compiled and installed Xen4.6 without remove the Xen4.4. Now the machine cannot boot normally. I mean booting stop at a sceen shows:
Loading Xen Xen.
WARNING: No Console will be available to OS.
Loading linux 3.13.0-24-generic ...
Loading initial ramdisk ...
Actually, I'm ok with this. Because I can still connect the dom0 using ssh before installing Xen 4.6. But after the installing, the network cannot be connected,

And the network configuration:
# The loopback network interface
auto lo em1 xenbr0
iface lo inet loopback
allow-hotplug xenbr0
iface xenbr0 inet static
address 172.16.105.204
netmask 255.255.255.0
network 172.16.105.0
broadcast 172.16.105.255
gateway 172.16.105.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 172.16.100.180
#bridge_ports em1
# The primary network interface
iface em1 inet manual
The network configuration works fine fine with xen4.4. But the network cannot connected after I compiled xen4.6, even after I removed xen4.4.
Is there anything wrong? I believe it's the problem of grub configuration. But I can't figure out where it is. Besides, can two xen version exists together on one host? I'm now regret in upgrading cause everything now seems in fuzzy and sucks.
