Hi, All
The vm can't start when using numa based on centos 6.5(kernel:
kernel-2.6.32-431.17.1.el6.x86_64,
qemu-kvm: qemu-kvm-0.12.1.2-2.415.el6_5.8.x86_64). My numa setting in vm
xml is the following:
--------------------
<numatune>
<memory mode='strict' nodeset='1'/>
</numatune>
--------------------
When 'nodeset' sets '0', the vm can start; However, when setting it to 1,
it can't start and report
the following error:
----------------------------
error: Failed to start domain testbsd
error: internal error Process exited while reading console log output: char
device redirected to /dev/pts/1
kvm_create_vcpu: Cannot allocate memory
Failed to create vCPU. Check the -smp parameter.
----------------------------
Any suggestions?
Thanks in advance...
Best Regards
Jarod
