salt.modules.xapi_virt

This module (mostly) uses the XenAPI to manage Xen virtual machines.

Big fat warning: the XenAPI used in this file is the one bundled with Xen Source, NOT XenServer nor Xen Cloud Platform. As a matter of fact it will fail under those platforms. From what I've read, little work is needed to adapt this code to XS/XCP, mostly playing with XenAPI version, but as XCP is not taking precedence on Xen Source on many platforms, please keep compatibility in mind.

salt.modules.xapi_virt.vm_cputime(vm_=None)

Return cputime used by the vms on this hyper in a list of dicts:

[
    'your-vm': {
        'cputime' <int>
        'cputime_percent' <int>
        },
    ...
    ]

If you pass a VM name in as an argument then it will return info for just the named VM, otherwise it will return all VMs.

CLI Example:

salt '*' virt.vm_cputime

salt.modules.xapi_virt.vm_diskstats(vm_=None)

Return disk usage counters used by the vms on this hyper in a list of dicts:

        'io_write_kbs'  : 0
        },
    ...
    ]

If you pass a VM name in as an argument then it will return info for just the named VM, otherwise it will return all VMs.

CLI Example:

salt '*' virt.vm_diskstats

salt.modules.xapi_virt.vm_info(vm_=None)

Return detailed information about the vms.

If you pass a VM name in as an argument then it will return info for just the named VM, otherwise it will return all VMs.

CLI Example:

salt '*' virt.vm_info

salt.modules.xapi_virt.vm_netstats(vm_=None)

Return combined network counters used by the vms on this hyper in a list of dicts:
