Re: [Xen-users] ping failing from master to guest hosts

[Zama Ques <queszama@xxxxxxxx>]

Hi Fajar ,

Thanks for replying back.

If I select the ip address as dhcp in the guest machines , then it could not retrive any ip address. It is blank .

Also, just to bring to notice is that while configuring the network in setting up the guest machines,
I could see only "Default" Network under "Virtual Network" Section.  And if I select "Shared Device" other than "Virtual Network" in the network section while creating the guest machines , I could not see any device . it was blank .

Please guide to troubleshoot further .

Thanks
Zaman

I'm pretty sure "virtual network" there means virbr0. Try using dhcp
on the guest as well, see what IP it gets.
