I don't necessarily want to upgrade the (to-be-)guest OS as it has some custom built software that cannot be recompiled. I did a flash archive of the original system, restored the image. There might be one caveat: /, var, opt, usr, export/home are all on separate slices on the original system and I gave them a smaller slice on the virtual machine as they don't need that much free space. I set up a virtual machine, a 64 bit one with x64 5/09 and earlier. The original machine is Dell Poweredge 1800 with two 8.8GHz Xeons and 16GB of RAM. The host system is a Win7 x64 with a Core i7 2600 and 32GB of RAM. I gave the guest 2GB (it ran fine for years with 1GB, it was upgraded for other reasons) The restore process itself is successful. When I try to boot the guest, it fails in 64bit mode. The Failsafe mode works fine, so it might be the problem of the 64 bit mode but the software we'd like to run (to be precise: archive and still be able to access) is compiled 64 bits. I was able to go to the kernel debugger and the process fails at the mentioned point (cpumod init) See also the attached screenshot and the logs.",defect,closed,VMM,VirtualBox 4.3.20,invalid,"VINF_EM_TRIPLE_FAULT, guru, cpumod init, solaris",,Solaris,Windows
