變更從機配置

欲修改從機的資源，請使用 hpvmmodify 命令。例如，若無法啟動從機 compass1，而產生下列訊息：

# hpvmstart -Pcompass1
HPVM guest compass1 configuration problems:
Warning 1: Insufficient free memory for guest.
Warning 2: Insufficient cpu resource for guest.
These problems may prevent HPVM guest compass1 from booting.
hpvmstart: Unable to continue.
#

欲修改有問題的從機 compass1 配置以移除虛擬 CPU 和記憶體，請輸入下列命令：

# hpvmmodify -Pcompass3 -c1 -r1GB
# hpvmstart -Pcompass1

VM 主機在建立從機後建立從機配置檔/var/opt/hpvm/guests/從機名稱。

Integrity VM 最多可建立三個從機配置檔：

vmm_config.current 包含目前設定的最新從機配置。
vmm_config.prev 包含最後已知的從機配置設定值。
vmm_config.next 包含自從機啟動後已變更的配置設定值。必須重新啟動從機方能使這些變更生效。
