Xen 於 OpenNEbual 的配置
1. 前提
- 已安裝 Xen 和 Xen Kernel
- /etc/init.d/xend 可以正常執行
- oneadmin 使用者可以執行 Xen 相關的指令
$ sudo vim /etc/sudoers %xen ALL=(ALL) NOPASSWD: /usr/sbin/xm * %xen ALL=(ALL) NOPASSWD: /usr/sbin/xentop * $ sudo /opt/drb/sbin/drbl-cp-host /etc/sudoers /etc/sudoers
2. Xen Driver 的檔案
- 主要有以下4個:
- $ONE_LOCATION/lib/mads/one_vmm_xen : Shell script wrapper to the driver itself. Sets the environment and other bootstrap tasks.
- $ONE_LOCATION/lib/mads/one_vmm_xen.rb : The actual XEN driver.
- $ONE_LOCATION/etc/vmm_xen/vmm_xenrc : environment setup and bootstrap instructions
- $ONE_LOCATION/etc/vmm_xen/vmm_xen.conf : set here default values for XEN domain definitions.
3.Xen Driver 的配置
- 告訴 ONE ,使用的 Hypervisior 是 Xen
$ sudo vim $ONE_LOCATION/etc/oned.conf IM_MAD = [ name = "im_xen", executable = "one_im_ssh", arguments = "im_xen/im_xen.conf", default = "im_xen/im_xen.conf" ] VM_MAD = [ name = "vmm_xen", executable = "one_vmm_xen", default = "vmm_xen/vmm_xen.conf", type = "xen" ]
- 上面設定檔的 IM 是 Information Manager,VM 是 Virtualization Managers
- name:driver 名稱,當加入 host 時會使用到
- executable:driver 的執行檔 (位於 $ONE_LOCATION/lib/mads)
- default:driver 的設定檔 (位於 $ONE_LOCATION/etc)
- type:視為 xen 的 driver
- 上面設定檔的 IM 是 Information Manager,VM 是 Virtualization Managers
- default file ($ONE_LOCATION/etc/vmm_xen/vmm_xen.conf),所有 domU 預設都會使用這些 attribute,也可視為 Template
- CPU=0.6
- CERDIT
- 附加的屬性: RAW = [ type="xen", data="on_crash=destroy" ]
- 範例檔
CPU = 1 MEMORY = 128 OS = [kernel="/path-to-kernel",initrd= "/path-to-initrd",root="sda1" ] DISK = [source="/path-to-image-file",target="sda",readonly="no"] NIC = [mac="xx.xx.xx.xx.xx.xx", bridg="eth0"] GRAPHICS = [type="vnc",listen="127.0.0.1",port="5900"]
- Run command file ($ONE_LOCATION/etc/vmm_xen/vmm_xenrc),包含了一些 Xen 指令路徑 (xm, xentop)
