Hi Jayapal,

I was able to "restart Network" clean, to rebuilt the VR. I have not had those issues in the last 10hrs. I can almost say that fixed my issue but not certain.

Thanks,
Motty

HI Motty,

First make sure there are no issue in the VM like ip addr, route, firewall etc.

Second When you send traffic from the VM, capture the it in each place to 
figure where exactly the traffic is blocking.
Is it reached to hypervisor, router etc ? This way you can find who is culprit.

Thanks,
Jayapal

Check routes on the guests that are having trouble. You should verify if the 
public traffic from these guests is reaching the router.

Subject: ACS 4.4.1 XenServer 6.2 - VMs lost connection in "Isolated" network

Hi All,

I have total of about 5 VMs on "Isolated" network, but they lost connection to 
outside world. I am able to ping the VR but can't ping to outside world. If I log in to 
VR, am able to ping anywhere outside or inside network.

out of the 5 VMs, 3 machines never loose connection, the two VMs that do loose 
connection are windows machines. To get the connection again, I have to restart 
VR. Any ideas?

I want to mentioned that, I have three other "Isolated" networks in the same zone. I do 
not have problems with other "Isolated" networks.

I do need help!

Thanks,
Motty
