Dear All,
am new to xen and recently implemented it.
i had some issues initially but googling arround and some wise replies from
you guys out there managed to clear them.
now I have 2 virtual machines on my xen domains
one is windows 2003 and other windows2008
both the virtual machines were working fine for about a week
jus 2 days back we had a change in our network . i mean we rearanged the
vlans so the linux host server which runs xen was moved to another vlan
then i fould that i could not ping the linux xen host . on further
investigations i fould that there was another file created for my ethernet
device
ifcfg-eth1.bak and also ifcfg-eth1 existed. the ifcfg-eth0 existed as before
the right config for my eth1 was there in ifcfg-eth1.bak file so i renamed
the ifcfg-eth1.bak to ifcfg-eth1 and did a network service restart and then
found that i could reach the xen host server . but fould that one of my
virtual server was shut
i tried to restart it in virt-manager but it gave a error although the other
virtual machine was running
so i tried to restart my linux xen host server and then found that the
virtual server which was running also had not started .
so i tried to start it and it would not start and after long time gives
error
here below i paste the error message
googling arround did not lead me to any possible solution
really would apprecite if any guys out there would advice and help
thanks and regards
simon
