I'm trying to add a new ip address to a running domain;

The domain starts:

[root@xen xenolinux-2.4.24]# xc_dom_create.py -f /etc/xc/test -D vmid=1
Parsing config file '/etc/xc/test'
VM image           : "/boot/xenolinux.gz"
VM ramdisk         : ""
VM memory (MB)     : "64"
VM IP address(es)  : "169.254.1.1"
VM block device(s) : "vd:2,/dev/xvda,w"
VM cmdline         : "ip=169.254.1.1:169.254.1.0:169.254.1.0:255.255.0.0::eth0:off root=/dev/xvda ro 4 VMID=1"
VM started in domain 1

Then I add the address:
xc_dom_control.py vif_addip 1 0 192.168.250.60

But no address is added.
This requires to have 2 hardware network(because 1 have only one)?

I also tried to add a new ip from the config file:
[root@xen xc]# xc_dom_create.py -f /etc/xc/test -D vmid=1 vif_addip 1 0 192.168.250.60
Parsing config file '/etc/xc/test'
VM image           : "/boot/xenolinux.gz"
VM ramdisk         : ""
VM memory (MB)     : "64"
VM IP address(es)  : "169.254.1.1; 192.168.250.60"
VM block device(s) : "vd:2,/dev/xvda,w"
VM cmdline         : "ip=169.254.1.1:169.254.1.0:169.254.1.0:255.255.0.0::eth0:off root=/dev/xvda ro 4 VMID=1"
VM started in domain 2

Thank you.

You've told Xen about the domain's new IP address, but you still
need to tell the domain itself in the normal way.

i.e. either log into the domain and "ifconfig eth0:1 192.168.250.60", or 
put the configuration runes in the
/etc/sysconfig/network-scripts/ifcfg-eth0:1 script (or whatever
the equivalent on your distribution is).

The linux kernel command line only allows you to configure a
single IP address, but if you don't need the 169.254.1.1 address
for other things you might want to configure the 192.168.250.60
address in the ip= line.

No, one will work just fine.

I'm trying to add a new address to a runing domain.
This is the domain:

[root@xen victor]# xc_dom_control.py list
Dom  Name             Mem(kb)  CPU  State  Time(s)
0    Domain-0          131072   0    r-      156
1    This is VM 1       65536   0    --       46

This is how I try to add the address:
xc_dom_control.py vif_addip 1 0 192.168.250.60

But no address apears:
eth0      Link encap:Ethernet  HWaddr AA:00:00:2F:57:69  
          inet addr:169.254.1.1  Bcast:169.254.255.255  Mask:255.255.0.0
    	  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
	  RX packets:97 errors:0 dropped:0 overruns:0 frame:0
	  TX packets:74 errors:0 dropped:0 overruns:0 carrier:0
	  collisions:0 txqueuelen:1000 
	  RX bytes:9906 (9.6 Kb)  TX bytes:11273 (11.0 Kb)
	
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
	  UP LOOPBACK RUNNING  MTU:16436  Metric:1
	  RX packets:12 errors:0 dropped:0 overruns:0 frame:0
	  TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
	  collisions:0 txqueuelen:0 
	  RX bytes:737 (737.0 b)  TX bytes:737 (737.0 b)

I suppose that the command "xc_dom_control.py vif_addip 1 0 192.168.250.60" only make internal routing.
So I added manualy the ip address, but it still not answering.

Thank you.

"xc_dom_control.py vif_addip" tells Xen about the new address,
but you'll still need to configure it in the domain with ifconfig.

>From within domain 1, did you ifconfig an alias with something
like the following?

 ifconfig eth0:60 192.168.250.60 netmask 255.255.0.0

You should then be able to ping 192.168.250.60 from within
domain 1, domain 0, and other the machines on the LAN.
