<p> am new to xen and recently implemented it. <br>i had some issues initially but googling arround and some wise replies from you guys out there managed to clear them. </p>
<p>now I have 2 virtual machines on my xen domains </p>
<p>one is windows 2003 and other windows2008 </p>
<p>both the virtual machines were working fine for about a week <br></p>
<p>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 <br>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 <br>
ifcfg-eth1.bak and also ifcfg-eth1 existed. the ifcfg-eth0 existed as before </p>
<p>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 </p>
<p>i tried to restart it in virt-manager but it gave a error although the other virtual machine was running </p>
<p>so i tried to restart my linux xen host server and then found that the virtual server which was running also had not started . </p>
<p>so i tried to start it and it would not start and after long time gives error </p>
<p>here below i paste the error message </p>
<p>googling arround did not lead me to any possible solution </p>
<p>really would apprecite if any guys out there would advice and help </p>
<p>thanks and regards </p>
<p>simon </p>
