Hi All: I am running SXCE b101, and used the following command to create a linux domU successfully: virt-install -n lss-kickstart1 --ram=2048 --vcpus=2 \ --os-type=linux --os-variant=rhel5 --bridge=nge1 \ --file=/dev/zvol/dsk/zfs_pool/xen/lss-kickstart1/root \ --file=/dev/zvol/dsk/zfs_pool/xen/lss-kickstart1/swap \ --file=/dev/zvol/dsk/zfs_pool/xen/lss-kickstart1/nfs \ --accelerate --paravirt --nographics \ --location=http://135.1.29.1/nfs/scientific/52/x86_64/ \ --extra-args="ks=http://135.1.29.1/nfs/xen_guest_sl52_x86_64_ks/kickstart/ks.cfg.1 ip=135.1.29.25 netmask=255.255.255.0 dns=135.1.1.111 gateway=135.1.29.254 noipv6" -d Now that everything is up and running, I would like to change the IP address of this domU to 135.1.29.1. I have no problem changing the files in domU, but it looks like XEN keeps using the old address. What (and/or how) do I change Xen to recognize the new address. (Note, I have no problem performing the changes while domU is down). thanks in advance, Paul -- This message posted from opensolaris.org

If it includes any IP configuration details (which is rare), they would need to be updated.
Hi David:
Using the virsh xmldump command, I don''t see any IP address info:

OK, I found it. Sorry, my mistake. Although I thought I changed the IP address in the virtual machine (and then rechecked it again), I still missed it. Not enough sleep I guess. Paul -- This message posted from opensolaris.org
