Hi, I've got 2 KVM guests; both running the current Ubuntu Quantal server test install (iso as of yesterday), and i'm trying to iSCSI boot one from the other (on a Ubunqu Quantal x86-64 host)
When I try to use the sanboot command on the client I do: sanboot iscsi:192.168.122.10:::1:iqn.2008-09.com.example:server1.share1 Could not open SAN device: Input/output error (http://ipxe.org/1d704439). Both VMs have 2 net interfaces; one in 192.168.122.x, and the other on 192.168.123.x; the server is 192.168.122.10/192.168.123.10. I've already dhcp'd OK, if I change any part of the iSCSI device name it gives a device not found error, so it's talking to the server. The 1st one ('server1') is running the 'tgt' iSCSI target stack, and serves a single LUN; here is it's config file: <target iqn.2008-09.com.example:server1.share1> backing-store /dev/mapper/server1-share1 </target> and is started with tgtd --iscsi portal=192.168.122.10,portal=192.168.123.10 in it's upstart script. The tgt is happy speaking to open-iscsi, indeed I've done a CD image boot of an install on the client vm and it's done the full install over iscsi, and I can bring up a 3rd VM and it get it to mount the iSCSI device and it can see it. There is a tcpdump capture here: http://www.treblig.org/debug/ipxe-tgt-sanboot.capture This trace is the result of running the sanboot command twice (the first one ending at packet 61 I think). The tcpdump was run on the server as tcpdump host 192.168.122.27 -s 16000 -w capture -U Looking at this in wireshark I can see multiple read capacities but I don't understand the last 4 packets of both sessions. This is just me trying stuff in VMs, but any suggestions are welcome.
