What can I do?
I forgot to mention that I can rescue the situation (avoid a reboot) by simply killing the second virtual box instance. The machine taht gets responsive again and even that SRS screen reappears after a minute or so. It was my understanding that a machine like an Ultra 20 with 4 GB should easily run 2-4 virtual Solaris (600 MB) instances. I have no problem upgrading to SAS disks and a more powerful machine as soon as I know that this basically works, but right now I am not convinced. One virtual machine (Solaris) works fine, even a Soalris geust and a Windows guest. But as soon as I start a second solaris guest, the machine goes down!? :-( The log file gives me again 00:17:33.825 PIIX3 ATA: execution time for ATA command 0xca was 46 seconds 00:18:18.556 TM: Giving up catch-up attempt at a 63964751518 ns lag; new total: 661419527113 ns 00:19:19.265 TM: Giving up catch-up attempt at a 60005285833 ns lag; new total: 721424812946 ns 00:20:21.576 TM: Giving up catch-up attempt at a 60870846281 ns lag; new total: 782295659227 ns 00:21:24.354 TM: Giving up catch-up attempt at a 60461477558 ns lag; new total: 842757136785 ns 00:22:58.934 TM: Giving up catch-up attempt at a 91367816914 ns lag; new total: 934124953699 ns 00:24:41.887 TM: Giving up catch-up attempt at a 103145242490 ns lag; new total: 1037270196189 ns Hints are greatly appreciated!
