Hi All,
This is a really strange behaviour on my Xen machine.
I have installed ubuntu HVM on a gutsy domain0 using
debootstrap.Reason for using debootstrap is that my Core 2 Duo machine
is unable to boot off ubuntu iso(s).So i used debootstrap for
installation.
I am facing some troubles with networking in HVM domainU.
1. The ethernet interface in domainU gets renamed everytime HVM
reboots or is booted again to ethX, where X is incremented every
reboot.
2. Second even if i manually assign IP address, gateway and dns
servers in HVM domain and restart the networking in domainU, i cannot
ping anyone except me.
FWIW, o/p of brctl show in domain0 is
luser@eagain:~$ brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.8a9591b9f217 no tap0
vif6.0
xenbr100 8000.000000000000 no
BTW what is xenbr100 here??
xm list shows,
luser@eagain:~$ sudo xm list
[sudo] password for luser:
Name ID Mem VCPUs State Time(s)
Domain-0 0 772 2 r----- 872.7
gutsy 6 128 1 -b---- 23.9
ifconfig in domain0 shows,
luser@eagain:~$ ifconfig

Also, i have assigned same class IP address to HVM domain viz
10.100.207.199 . Still i cannot ping gateway or domain0.
Neither is domain0 able to ping HVM domain.
Normal networking works fine in domain0.
Did anyone land into this trouble?
Where should i start looking to get a solution?
Any help or pointers will be greatly appreciated.
Thanks,
Pradeep

Hi,
I was able to solve the problem by passing the MAC Address in hvm
config file.Now i am able to ping the gateway and domain0 but not he
dns servers, though the entry is made in resolv.conf in HVM domain.
Any pointers on this will be appreciated.
Thanks,
