+ Usage: $0 [-f FILE_PATH] [-d DISK_SIZE] [-v BRIDGE_NAME] [-m BRIDGE_NAME] [-p BRIDGE_NAME]
+ [-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
