Host is OEL5.6 x86_64, guests are OEL5.7 x86. Not using 64bit guests because CPUs are the older AMD Opteron 248 that don't have hardware virtualization. I have told VB not to use HW virtualization, see ""Hardw. virt.ext: off"" in the attached showvminfo.txt file. I have three VMs: oel57net has 500M RAM, this never fails. It doesn't do much: acts as a DHCP and DNS and NFS server for the other two. oel57a and oel57b have 1500M RAM and fail regularly but unpredictably with a Guru Mediatation 1103. They never last more 15 minutes, they usually last at least 5 minutes. I had thought that the problem was to do with the software I am running (I'm building a Oracle 11.2 cluster) but I do not believe this: the failures sometimes occur before starting the clusterware daemons. I previously raised this issue on the forum when I was using VB release 4.1.12 this is the link tio the post https://forums.virtualbox.org/viewtopic.php?f=7&t=49184&p=223700&hilit=guru+meditation+1103#p223700 which includes more examples of the problem. Please tell me any other information I can provide, and thank you for any assistance.",defect,closed,other,VirtualBox 4.1.18,obsolete,Guru Meditation 1103,,Linux,Linux
