Environment: S10u6 patched to 138889-08 on AMD Opteron 2376, 4Gb memory. VirtualBox 3.0.2 r49928 for SunOS. Started Win2k8 and Ubuntu guests headless (with HW virtualization enabled). System hard hangs after about 3 hours runtime. Could not break console to MDB (system was booted w/debugger enabled). System does not character echo nor respond to network (ping). No disk activity observed. Same hang happened almost immediately after starting 3 guest VMs concurrently. All VMs had HVM enabled with one CPU allocated to each guest (IO Apic enabled). This configuration had been running solidly under VB 2.2.2 for months uptime. No entries were noted in either the VM logfile(s) nor syslog. Guests could be resumed after host is rebooted. Currently reverting to 2.4.x.",defect,closed,VMM,VirtualBox 3.0.2,fixed,,,other,Solaris
