Live filter search

The idea is not just to provide a good search engine, but also a complete solution for managing all your XenServer infrastructure. Ideally:

  • less clicks to see or do what you need
  • find a subset of interesting objects
  • perform bulk actions on all results found
  • sort your results for more pertinent insight

Pro Tip: the URL of Xen Orchestra contains the search string, eg home?s=power_state%3Arunning+. You can share these URLs to your colleagues to share your search!

Search examples

We include some predefined filters in the dropdown "Filters":

You can use custom filters here:

If you want to record your filter, just click on the "Save" icon

After giving a name to your filter, you will be able to find it in the dropdown filter menu.

Just go into your user panel (bottom of main left menu):

There, you can edit or remove any filter/search you've created!

In this user section, you can set a default filter (preset filters or your own).

Pro Tip: this is saved in your user preferences. It means that you can connect anywhere on any browser, and you'll still see the same behavior.

Filter syntax

A filter allows you to search through a collection of objects which have multiple properties and may even contain other nested objects.

Searching for a string (or substring)

Simply type the string, if it contains special characters just surround it with quotes:

  • simple-string
  • "string with special characters like whitespaces"

The search is recursive, case insensitive and non-anchored (i.e. matches if the pattern is contained in a string).

A simple string can also contain a wildcard character (*) to match any character in a portion of the string:

  • foo*bar: matches foobar, foo - bar, etc.

Regular expression

For more advanced string matching, you can use regular expressions:

  • /^DNS server \d+$/: matches DNS server 1, DNS server 05 but not DNS server
  • /foo/i: with the i flag, it ignores the case, therefore it matches Foo and FOO

More information about supported regular expressions.

Searching a specific property

Type the property name, followed by a colon : and a subfilter:

  • name_label:"my VM"
  • virtualizationMode:hvm
  • boot:order:cn


Prefix your filter with an exclamation mark ! to exclude any matching results:

  • !hvm
  • !power_state:Running or power_state:!Running


Simply type the filter's terms side by side:

  • power_state:Halted !virtualizationMode:hvm


Parentheses can be used to group terms together:

  • !(power_state:Running virtualizationMode:hvm)


Pipe | followed by a group of terms:

  • |(vm1 vm2)
  • power_state:|(Running suspended)

Truthy property

This one is less common but can be used to check whether a property has a truth-like value (true, non-empty string or non-zero number).

Postfix the name of a property by a question mark ?:

  • auto_poweron?
  • high_availability?

Number comparison

You can use the search field/filter with number comparisons:

  • snapshots:length:>2 (to display VMs with more than 2 snapshots)
  • $VBDs:length:>=4 (VMs with more 4 or more disks attached)
  • VIFs:length:>=2 (number of network interfaces)

Available properties

There isn't much documentation listing these (yet), but you can see all objects and their properties using xo-cli --list-objects. You can then use these properties for search in XOA.

Take a look at the documentation for xo-cli :)

Example: to search by the Xen Tools status:

  • xenTools?: whether the tools are installed
  • xenTools:"up to date": whether they are installed and up to date
