Oracle VM 3 如何線上 add CPU / add memory

特別是在Oracle VM online document沒有看到太多文件, 因為知道OVM是基於Xen Server

去改的, 所以就上網找一下關於Xen Server的步驟啦...

 

[root@ ovs01 ~]# xm list

Name                                        ID   Mem VCPUs      State   Time(s)

0004fb0000069991df26eff8            76 2300     6     -b----   2443.8

Domain-0                                     0 11474    20     r----- 266098.2

xm mem-set 0004fb0000069991df26eff8 4500  (單位為 MB, 把記憶體從2300MB 放大到4500MB)

 

xm list

vcpu-set 0004fb0000069991df26eff8 16 (從CPU 從 6個 vCPU 放大到16個 vCPU)
