[-k PARAMS] [-r RAM] [-i|-c] [-w] [-b]
|
|
|
|
Installs XenServer OpenStack VPX.
|
|
|
|
OPTIONS:
|
|
|
|
-h Shows this message.
|
|
-i Install OpenStack VPX as template.
|
|
-c Clone from existing template.
|
|
-w Wait for the network settings to show up before exiting.
|
|
-b Enable memory ballooning. When set min_RAM=RAM/2 max_RAM=RAM.
|
|
-f path Specifies the path to the XVA.
|
|
Default to ./os-vpx.xva.
|
|
-d disk-size Specifies the size in MiB for the data disk.
|
|
Defaults to 500 MiB.
|
|
-m bridge Specifies the bridge for the isolated management network.
|
|
Defaults to xenbr0.
|
|
-v bridge Specifies the bridge for the vm network
|
|
-p bridge Specifies the bridge for the externally facing network.
|
|
-k params Specifies kernel parameters.
|
|
-r MiB Specifies RAM used by the VPX, in MiB.
|
|
By default it will take the value from the XVA.
|
|
|
|
EXAMPLES:
|
|
|
|
Create a VPX that connects to the isolated management network using the
|
|
default bridge with a data disk of 1GiB:
|
|
install-os-vpx.sh -f /root/os-vpx-devel.xva -d 1024
|
|
|
|
Create a VPX that connects to the isolated management network using xenbr1
|
|
as bridge:
|
|
install-os-vpx.sh -m xenbr1
|
|
|
|
Create a VPX that connects to both the management and public networks
|
|
using xenbr1 and xapi4 as bridges:
|
|
install-os-vpx.sh -m xenbr1 -p xapi4
|
|
|
|
Create a VPX that connects to both the management and public networks
|
|
using the default for management traffic:
|
|
install-os-vpx.sh -m xapi4
|
|
|
|
Create a VPX that automatically becomes the master:
|
|
install-os-vpx.sh -k geppetto_master=true
