Hi, I have a v20z host biprocessor with 6Gb RAM running Solaris 10 10/08 s10x_u6wos_07b X86. For many reasons, at the moment I cannot start using zones to solve my problem, so to quickly get a running solution I decided to us VBox on this solaris machine, running another Solaris 10 guest on it. The guest OS uses 1 cpu and 2 Gb RAM, it runs in headless mode, host interface network (plumbed and unconfigured bge:x interface). At startup the system works fine for almost 1-2 days, then it starts slowing down a lot, until it's almost unusable: even an ssh session would respond very slow on every command. Restarting the guest system doesn't solve. I have to init 5 the guest system, wait for vboxheadless to die on host and run again, or actually init 6 the host system too. The host system respond very fast in every situation, it runs just OS, ipfilter on the 2 physical interfaces (1 public, 1 private), named, mysql+bacula. The guest system runs a lot of network services (apache2, 2 tomcat instances, postgres, postfix+amavis+spamassassin+clamav, cyrus, samba, webmin, bacula agent). >From time to time, restarting the entire system, some of the services don't >start correctly, and I have to restart them manually (usually amavis or >apache2). I also experienced some system crash after some minutes the system restarted, with null pointers on kernel, but no kernel dump was available. Is there any way I should optimize vbox startup for solaris guest on solaris host to avoid the slow down? I also have these 2 messages on guest startup: - NOTICE: MPO disabled because memory is interleaved - WARNING: BIOS microcode patch for AMD Athlon(tm) 64/Opteron(tm) processor erratum 109 was not detected; updating your system's BIOS to a version containing this microcode patch is HIGHLY recommended or erroneous system operation may occur.
