This configures how the toolstack handles requests to put a VM to S3. Note that this doesn't affect requests made from within guest, but just requests originating from the UI / closing the laptopt laptop lid etc. It can be one of the following:
...
- XenMgr/Connect/* - wrappers to access other daemons in the system
- XenMgr/Expose/* - entry points for all xenmgr's dbus server rpcs
- XenMgr/CdLock.hs - relatively new code for handling the AFRL request cd drive lock model
- XenMgr/Config.hs - global xenmgr config storage/query
- XenMgr/Diagnostics.hs - gathering status reports from vms + other diagnostics
- XenMgr/Diskmgr.hs - vhd creation
- XenMgr/Errors.hs - definition of numbered errors reported to the UI
- XenMgr/Host.hs - lots of host level query functions (eth0 mac adreesesadresses, bios versions, xc versions, update state etc)
- XenMgr/HostOps.hs - host shutdown/sleesleep/hibernate/reboot entry points
- XenMgr/PowerManagement.hs - actual implementation of host shutdown/sleep/hibernate/reboot etc plus code to handle lid state changes
- XenMgr/Notify.hs - wrappers for easier generation of various dbus signals
- XenMgr/Rpc.hs - definition of Rpc monad used in xenmgr for dbus access
- XenMgr/XM.hs - definition of XM monad based on reader monad containing context forall vms. Useful for doing some cross vm interactions which require locking / synchronization
...
you can put the following parameters in your config file:
(common options)
| key name | type | description |
|---|
| hvm | s | command line given to the kernel |
| startup | s | specify what to do with the domain at startup possibles value: started, paused, shutdown or restore |
| debug | b | logs all operations to /tmp/xenvm-debug-%uuid |
| uuid | s | specify the domain uuid (default to autogeneration) |
| on_crash | s | specify the action to be taken after notifying a |
| on_halt | s | crash/halt/reboot. possible values: |
| on_reboot | s | preserve, reboot, destroy |
| kernel | s | specify where to find the kernel to boot (can be empty for hvm. default to hvmloader) |
| memory | i | specify the memory given to the guest in megabytes |
| vcpus | i | number of vcpus available to the guest |
| disk | s | add a virtual disk. |
|
|
| format: physpath:phystype:virtpath:mode:devty[:k=v...] |
| |
|
| - physpath: path to the disk image, raw device, .. |
| | | | | | | |
|
| - extra k=v arguments (cipher, key-size, key-file) |
| nic | s | add a virtual nic. |
| |
|
| format: key=value,key=value,... (can be empty) |
| |
|
| supported key: bridge, mac, id |
| | | |
|
| "nic = bridge=xen-br0,mac=ab:ef:fe:dc:ba:ab" |
|
|
| "nic = mac=ab:ef:fe:dc:ba:ab" |
| |
|
| "nic = " |
| pci | s | add a pci device. |
| |
|
| format: devid,bind,domain:bus device.function |
| serial | s | redirect serial to device or network tcp:ip:port |
| |
|
| ex: "pty" or "tcp:1.2.3.4:1234" |
| display | s | details the type of display available for the guest |
| |
|
| format: :key[=value],key[=value],... |
| | | |
|
| - vnc (keys allowed: use-port-unused, keymap, port) |
| | | | (the following are just useful for pv)
| key name | type | description |
|---|
| cmdline | s | command line given to the kernel |
| initrd | s | specify the initrd use, leave empty for none |
(the following are just useful for hvm)
| key name | type | description |
|---|
| pae | b | specify that the guest is using PAE |
| acpi | b | specify that the guest is using ACPI |
| apic | b | specify that the guest is using APIC |
| nx | b | specify that the guest is using NX |
| smbios-pt | b | specify that the guest is using smbios pass-through |
| smbios-oem-type-pt | i | tables number to passthrough |

| boot | s | specify the qemu boot string |
| extra-hvm | k=v | specify extra arguments passthrough to qemu as -k v |
| power-management | i | specify the power management passthrough mode |
| |
|
| - 1 : pass-through mode (limited scope) |
| |
|
| - 2 : non pass-through mode (in doubt use this) |
| oem-features | i | specify whether or not to pass through oem features. |
| |
|
| Note: At the moment any integer value can be passed |
|
|
| but this is likely to change in future especially if |
| |
|
| we decide to pass through a subset of oem features |
| |
|
| and let user configure that subset. |
| timer-mode | i | specify the timer mode used. |
| timeoffset | s | specify the time offset (i.e. timezone) used. |
| pci-msitranslate | i | specify whether to use MSI-INTx translation for guest. |

| |
|
| for passthrough devices. |
| inject-sci | i | specify whether or not to inject SCIs like lid close, |
| |
|
