This section lists bugs that have been fixed since the previous Oracle VM Server for SPARC (or Logical Domains) software release.
The following Logical Domains requests for enhancements (RFEs) and bugs were fixed for the Oracle Solaris 10 9/10 release.
Add a domain service to support OS identification - solaris
RFE: Want a mechanism for Solaris to know if it is an LDOM and if so what type
vdc_init_attr_negotiation() should compare msglen to the size of vd_attr_msg_t not vio_ver_msg_t
DVD-ROM (not OS installation disk) can not mount from guest domain of LDOM 1.0.2
RFE: Need information about control domain from within a guest domain
Ambiguous treatment of offline cpus with respect to DR
add memory dr feature to ldoms
vdisk failover should handle storage/storage-path failures (a la mpxio)
Solaris should support cooperative migration
cpu DR incorrectly rejects some attempts to remove vcpus
Logical Domains Agents
Recursive mutex panic when failures from hv_ldc_rx_set_qhead() are not handled properly.
i_ldc_rxq_drain should not call i_ldc_set_rx_head if the queue is empty
service domain panics when exporting a file as a single-slice disk
RFE: unique ID for LDOMs to facillitate asset tracking
a domain running Sun Cluster should notify the cluster framework when it is migrating
In elastic mode, a guest at the reboot menu can stall ldm commands
User level Domain service loopback client registration fails in some scenarios
iostat within guest domains report 100% busy following a control domain reboot
deadlock with mdeg_notify_clients and mdeg_unregister hit with DEBUG, causes login hang
vdisk using failfast or multipath can hang during heavy I/O
vdisk does not timeout when backend does not exist
domain can panic on 'ldm stop'

The following Oracle VM Server for SPARC 2.0 RFEs and bugs were fixed for the Oracle VM Server for SPARC 2.0 software release:
ldmd does not report MAUs (CPUset) in order.
LDom Manager needs to parse components portion of PRI for rcid
set-vcc prevented when system already in del-reconf mode
ldm ls -o checks are not consistent; some check 2 letters, some check the entire key
RFE: LDoms Manager should support cooperative migration
ldmp2v should support root file system on slices other than s0
“WARNING: ncp1: only one instance (0) allowed” seen on doing P2V migration of a sun4u to N2/VF
ldmp2v prepare usage message could be improved
DRM: an enabled policy may not decrease cpu count when it needs to
DRM: bit of inconsistency in assigning tod-begin and tod-end parameter values
ldmd core dumps on upgrade from 1.2 patch-02 to 1.3 when inactive domains are in existence.
ldmp2v: Flash archiving method should support excluding file systems, directories and files
ldmp2v should be aware of /var/fm

DRM policy handle mismatch with manual
ldmp2v(1M) collect phase should not ufsdump(1M) on actively mounted FS.
PM legacy memory leaks plus clean-up
Mount vdisks on files with -o nologging
“ldm migrate-dom” is not correctly interpreted
DRM: is not reducing vcpus down to 'min-vcpu' on systems that are basically idle (%util=0.1)
code to get PM policy should not retry every second when SNMP support can't be initialized
LDoms configuration GUI needs to be updated with Oracle branding
