Setting up Logical Domains, part 2
In part 1, I talked about the server side of Logical Domains. This time, I'll cover how I set up a guest domain.
First, I have created a zfs pool called storage on the host, and I'm going to present a zvol (or maybe several) to the guests.
I'm going to create a little domain called ldom1.
ldm add-domain ldom1
ldm set-core 1 ldom1
ldm add-memory 4G ldom1
ldm add-vnet vnet1 primary-vsw0 ldom1
Now create and add a virtual disk. Create a dataset for the ldom and a 24GB volume inside it, add it to the storage service and set it as the boot device.
zfs create storage/ldom1
zfs create -V 24gb storage/ldom1/disk0
ldm add-vdsdev /dev/zvol/dsk/storage/ldom1/disk0 ldom1_disk0@primary-vds0
ldm add-vdisk disk0 ldom1_disk0@primary-vds0 ldom1
ldm set-var auto-boot\?=true ldom1
ldm set-var boot-device=disk0 ldom1
Then bind resources, list, and start:
ldm bind-domain ldom1
ldm list-domain ldom1
ldm start-domain ldom1
You can connect to the console by looking at the number under CONS in the list-domain output:
# ldm list-domain ldom1
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
ldom1 bound ------ 5000 8 4G
# telnet localhost 5000
Connected to localhost.
Escape character is '^]'.
Connecting to console "ldom1" in group "ldom1" ....

Attempt to boot it off the net and it says:
Requesting Internet Address for 0:14:4f:f9:87:f9
which doesn't match the MAC address in the console output. So if you want to jumpstart the box, and that's easy enough, you need to do a 'boot net' first to get the actual MAC address of the LDOM to add it to your jumpstart server.
To add an iso image to boot from:
ldm add-vdsdev options=ro /var/tmp/img.iso iso@primary-vds0
ldm add-vdisk iso iso@primary-vds0 ldom1
At the ok prompt, you can issue the 'show-disks' command to see what disk devices are present. To boot off the iso:
And it should work. This is how I've been testing the Tribblix images for SPARC, by the way.
