Increase Loopback devices
|
| The number of DomainsU that can be started at the same time in CentOS 5 is 5 Domains. It is a cause that the number of loop back devices on Domain0 is insufficient. If you want to start more than 6 DomainUs, increase loop back devices on Domain0. |
|
[root@ns ~]# vi /etc/modprobe.conf # add at the bottom options loop max_loop=32 [root@ns ~]# for i in `seq 8 31`; do mknod -m660 /dev/loop$i b 7 $i; done [root@ns ~]# chown root:disk /dev/loop*
|
| It's OK, many DomainUs can run like below. |
|
[root@ns ~]# xm list Name ID Mem(MiB) VCPUs State Time(s) Host 0
