get_ajax_console(f)

get_available_resource()

Updates compute manager resource info on ComputeNode table.

This method is called when nova-coompute launches, and whenever admin executes “nova-manage service update_resource”.

get_console_output(instance)

get_console_pool_info(console_type)

get_cpu_info()

Get cpuinfo information.

Obtains cpu feature from virConnect.getCapabilities, and returns as a json string.

Returns:see above description

get_diagnostics(instance_name)

get_disks(instance_name)

get_host_stats(refresh=False)

Return the current state of the host. If ‘refresh’ is True, run the update first.

get_hypervisor_type()

Get hypervisor type.

Returns:hypervisor type (ex. qemu)

get_hypervisor_version()

Get hypervisor version.

Returns:hypervisor version (ex. 12003)

get_info(instance)

Retrieve information from baremetal for a specific instance name.

If a baremetal error is encountered during lookup, we might raise a NotFound exception or Error exception depending on how severe the baremetal error is.

get_interfaces(instance_name)

get_local_gb_total()

Get the total hdd size(GB) of physical computer.

Returns:The total amount of HDD(GB). Note that this value shows a partition where NOVA-INST-DIR/instances mounts.

get_local_gb_used()

Get the free hdd size(GB) of physical computer.

Returns:The total usage of HDD(GB). Note that this value shows a partition where NOVA-INST-DIR/instances mounts.

get_memory_mb_total()

Get the total memory size(MB) of physical computer.

Returns:the total amount of memory(MB).

get_memory_mb_used()

Get the free memory size(MB) of physical computer.

Returns:the total usage of memory(MB).

get_pty_for_instance(instance_name)

get_vcpu_total()

Get vcpu number of physical computer.

Returns:the number of cpu core.

get_vcpu_used()

Get vcpu usage number of physical computer.

Returns:The total number of vcpu that currently used.

See comments of same method in firewall_driver.

unrescue(f)

update_host_status()

Update the status info of the host, and return those values to the calling program.

class HostState(connection)

Bases: object

Manages information about the XenServer host this compute node is running on.

get_host_stats(refresh=False)

Return the current state of the host. If ‘refresh’ is True, run the update first.

update_status()

We can get host status information.
