[Xen-users] Virtual interface problems

["sadique@xxxxxxxxxxxxxxxxxxx" <sadique@xxxxxxxxxxxxxxxxxxx>]

Hi Everyone,

Hope you are all well..

I have some problems to configure bandwidth monitoring for domains in an 
xen vps......
Suppose we have three domains..... The ifconfig entry will something 
like this
vif1.0    Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:3691 errors:0 dropped:0 overruns:0 frame:0
         TX packets:412527 errors:0 dropped:776 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:435348 (425.1 Kb)  TX bytes:24588202 (23.4 Mb)

vif2.0    Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:4894 errors:0 dropped:0 overruns:0 frame:0
         TX packets:412178 errors:0 dropped:667 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:477402 (466.2 Kb)  TX bytes:25068366 (23.9 Mb)

vif3.0    Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:64606 errors:0 dropped:0 overruns:0 frame:0
         TX packets:376113 errors:0 dropped:610 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:18405141 (17.5 Mb)  TX bytes:73257575 (69.8 Mb)

Only the specific part taken.... When we stop and start all these 
domains it will be vif4.0, vif5.0, vif6.0 and if we restrat once again 
it would take the next three digits and will be going up. Only a system 
reboot would bring this to its first stage...
So really bandwidth monitoring seems to be a horrible task... I use the 
contents of /proc/net/dev as mrtg collects data from there... So if i 
restart a domain i must make related changes in mrtg config files....
Any one any idea how to make this interface name permanent for a 
domain....  All suggestions are accepted....
Please bear the ignorance of a newbie :-(

Thanks
Sadique
