redhat下安装虚拟机问题解决

1.[root@rhel7 redhat7]# virsh define libvirt.xml

Domain redhat7 defined from libvirt.xml

[root@rhel7 redhat7]# virsh start redhat7

error: Failed to start domain redhat7

error: internal error: early end of file from monitor: possible problem:

Cannot set up guest memory 'pc.ram': Cannot allocate memory

网上没找到办法，把libvirt.xml 的内存和cpu都改小，重新安装虚拟机就好了。
