Message-ID: <4B220ADF.6030709@gmail.com> (raw)
Does anybody have a glue why process are not able to allocate more than
3.6GB memory ?
What should i do to allow process allocate more than 3.6GB memory? Is it
possible at all?
I have hostserver:
linux kernel: 2.6.30.9 (arch amd64)
RAM: 64GB
CPUs: 2xQuadCore AMD Opteron 2378
Then I have several kvm guests on it, like:
linux kernel: 2.6.30.4 (arch amd64)
RAM: 6GB
CPUs: 2xQEMU Virtual CPU version 0.9.1 (vendor: AuthenticAMD)
cpu flags: fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat
pse36 clflush mmx fxsr sse sse2 syscall nx lm pni hypervisor
VM use virtio for net and block drivers.
