I got err message :
Failed to allocate memory: Resource temporarily unavailable
-bash: fork: Not enough space
.
the same ietmes happen on OmniOS , the following is a OmniOS-discuss mail .
That caused by availrmem not enough for memory locked .
Is that mean I can only use about 14G memory for KVM VM in a 32G memory
installed server?
OS can only locked about 14G memory .
——FOLLOWING--
Hello, guys：
I has a server running OmniOS v11 r151016. the server have 32G memory .
I star tow kvm virtual machines by running the following commands:
qemu-system-x86_64 -enable-kvm -vnc 0.0.0.0:12 -cpu host -smp 4 -m 8192 -no-hpe
qemu-system-x86_64 -enable-kvm -vnc 0.0.0.0:11 -cpu host -smp 2 -m 4096 -no-hpe
one use 8G memory and the other one use 4G memory.
now the memory usage of the system as following:
root@BLCC01:/root# prtconf | grep Memory
Memory size: 32760 Megabytes
root@BLCC01:/root# echo "::memstat" | mdb -k
