Communication Error With Virtual Disk Server Using Port 0. Retrying
Chartre-Oracle on Jun 13, 2011 Oracle VM Server for SPARC 2.1 (aka LDoms 2.1) has been recently released. One of the major new features of this release is live migration; you can find more information about this cool feature on Liam's blog, and some experiment on Jeff's blog. Here, I would like to talk about a much more modest improvement but which is actually very useful: the device validation. Device Misconfiguration and Previous Versions of LDoms Previous versions of LDoms are not very friendly for handling some obvious configuration mistakes, like a misspelled path to designate a virtual disk backend. For example, let say I have a virtual disk with a Solaris 11 installation which is on the ZFS volume ldoms/vdisk/solaris_11. If I want to use this ZFS volume as a virtual disk then I have to add the device /dev/zvol/rdsk/ldoms/vdisk/solaris_11 to the virtual device server (vds) with the following command: # ldm add-vdsdev /dev/zvol/rdsk/ldoms/vdisk/solaris_11 s11@primary-vds0 If I make a mistake in the path of the device, for example I forget the 's' at the end of 'ldoms', then the system will not complain and I will be able to successfully create and configure my domain: # ldm create ldg1 # ldm set-vcpu 8 ldg1 # ldm set-mem 8G ldg1 # ldm add-vnet vnet0 primary-vsw0 ldg1 # ldm add-vdsdev /dev/zvol/rdsk/ldom/vdisk/solaris_11 solaris_11@primary-vds0 # ldm add-vdisk vdisk0 solaris_11@primary-vds0 ldg1 # ldm bind ldg1 # ldm start ldg1 However, if I access the console of my guest domain ldg1 and try to boot it, I am getting some obscure messages but my domain is definitively not booting: # telnet 0 5001 Trying 0.0.0.0...
