Ovirt and power saving
Hello, I would like to ask if it is possible to do this use case with ovirt: 1) two servers powered on 2) operator suspend some virtual machines 3) load falls down 4) ovirt shutdown one server Then operator unpauses virtual machines and ovirt starts again the 2nd server. Thanks, Mario
We have power saving policy that also have possibility to poweroff hosts(via power management), you can configure power saving policy parameters for you purpose(HighUtilization can have values from 50-100 and LowUtilization 0-49), so you can set LowUtilization=0 and HighUtilization=50, so load balancing will try migrate all vms on one host(if cpu utilization less that 50). And also you can set parameter "HostsInReserve" to 0 if you do not want additional hosts in reserve. ----- Original Message ----- From: "Mario Giammarco" <mgiammarco@gmail.com> To: users@ovirt.org Sent: Tuesday, January 13, 2015 1:30:38 PM Subject: [ovirt-users] Ovirt and power saving Hello, I would like to ask if it is possible to do this use case with ovirt: 1) two servers powered on 2) operator suspend some virtual machines 3) load falls down 4) ovirt shutdown one server Then operator unpauses virtual machines and ovirt starts again the 2nd server.

Thanks for reply. I just want now to be sure that you can pause vm and so trigger the low utilization parameter 2015-01-13 12:45 GMT+01:00 Artyom Lukianov <alukiano@redhat.com>:

I mean that I know that I can set a power saving policy, it is a very nice thing. I need to be sure that I can pause/suspend (not shutdown) virtual machines. I also need that, if I suspend enough virtual machines ovirt shutdowns server to save power following the power save policy. Otherwise is it possible to manually shutdown a server forcing ovirt to migrate vms to the only one powered up? Basically it is a "manual power saving" mode. Thanks again, Mario 2015-01-13 14:21 GMT+01:00 Artyom Lukianov <alukiano@redhat.com>:

Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled. Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt? After that, try starting VM with hostdev element added to XML.

With nodedev we just see device nodes, pretty difficult to identify, even with --tree opt :
usb_1_0_1_0 usb_1_1 usb_1_1_1_0 usb_1_1_4 usb_1_1_4_1_0 usb_1_1_4_1_1 usb_1_1_6 usb_1_1_6_1 usb_1_1_6_1_0 usb_1_1_6_1_1_0 usb_1_1_6_1_1_1 usb_1_1_6_1_1_2 usb_2_0_1_0 usb_2_1 usb_2_1_1_0 usb_usb1 usb_usb2
The xml injected is, I think right :
<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x0572'/> <product id='0x1321'/> </source> </hostdev>
Even with The device on the VM xml, the device does'nt appears in the Windows VM.
How do you check it in the guest? can you try that with Linux guest to see if any device whatsoever shows up? Thanks, michal

Hi, I've tried also to inject the device with virsh attach-device, all seems to work but nothing happen in the VM :
[root@unc-srv-hyp2 ~]$ virsh attach-device unc-srv-prnt3 usb-modem.xml Please enter your authentication name: root Please enter your password: Device attached successfully
What did I do wrong, any ideas ?
Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled.
Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt?
After that, try starting VM with hostdev element added to XML.

Hi,
Can you tell me if I can use an USB modem through one of the hypervisor hosts to a Windows VM ?
I’d like to install a Windows Fax Server.
Thank you for your answers.
should be possible using qemu args: -usbdevice host:vendor_id:product_id
in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:
<domain type='kvm'> <name>...</name> … <devices> … <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x@VENDOR@'/> <product id='0x@DEVICE@'/> </source> </hostdev> </devices> </domain>
if this option is not exposed in ui you can use vdsm-hooks[1] to modify the libvirt configuration and inject such device.
Regards, Alon

Simply save it into something like listdevices.py and run $ python listdevices.py. It will list libvirt XML for all of the devices, you just need to find correct vendor id/product id for your usb device and then use the name for detach e.g. nodedev-detach usb_usb0.

Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled.
Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt?
After that, try starting VM with hostdev element added to XML.

Simply save it into something like listdevices.py and run $ python listdevices.py. It will list libvirt XML for all of the devices, you just need to find correct vendor id/product id for your usb device and then use the name for detach e.g. nodedev-detach usb_usb0.

Hi, I'm sure of the device, it's clearer with lsusb, you see all the infos about the device :
Bus 001 Device 006: ID 0572:1321 Conexant Systems (Rockwell), Inc. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 2 Communications bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0572 Conexant Systems (Rockwell), Inc. idProduct 0x1321 bcdDevice 1.00 iManufacturer 1 Conexant iProduct 2 USB Modem iSerial 3 24680246 bNumConfigurations 2 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 73 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4
With nodedev we just see device nodes, pretty difficult to identify, even with --tree opt :
usb_1_0_1_0 usb_1_1 usb_1_1_1_0 usb_1_1_4 usb_1_1_4_1_0 usb_1_1_4_1_1 usb_1_1_6 usb_1_1_6_1 usb_1_1_6_1_0 usb_1_1_6_1_1_0 usb_1_1_6_1_1_1 usb_1_1_6_1_1_2 usb_2_0_1_0 usb_2_1 usb_2_1_1_0 usb_usb1 usb_usb2
The issue is, you need to get libvirt name of the device and run the nodedev-detach - have you done that with no success?
If not, use some simple script such as (python)
import libvirt
conn = libvirt.openReadOnly() devices = conn.listAllDevices() for dev in devices: print dev.XMLDesc()
to easily find the device and use the <name> element for nodedev-detach call. That should handle unbinding it from the driver and possibly binding it to some usb stub if that exists. If that doesn't fix it, I admit that I'm not sure what could be the cause apart from OS/hw.
The xml injected is, I think right :
<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x0572'/> <product id='0x1321'/> </source> </hostdev>
Even with The device on the VM xml, the device does'nt appears in the Windows VM. Regards Alain

Ok Martin, I'll try the python script, but I'm a newbie in python, which argumenet I need to put to execute it ? Thank you Alain
Simply save it into something like listdevices.py and run $ python listdevices.py. It will list libvirt XML for all of the devices, you just need to find correct vendor id/product id for your usb device and then use the name for detach e.g. nodedev-detach usb_usb0.

Hi, I'm sure of the device, it's clearer with lsusb, you see all the infos about the device :
Bus 001 Device 006: ID 0572:1321 Conexant Systems (Rockwell), Inc. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 2 Communications bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0572 Conexant Systems (Rockwell), Inc. idProduct 0x1321 bcdDevice 1.00 iManufacturer 1 Conexant iProduct 2 USB Modem iSerial 3 24680246 bNumConfigurations 2 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 73 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4
With nodedev we just see device nodes, pretty difficult to identify, even with --tree opt :
usb_1_0_1_0 usb_1_1 usb_1_1_1_0 usb_1_1_4 usb_1_1_4_1_0 usb_1_1_4_1_1 usb_1_1_6 usb_1_1_6_1 usb_1_1_6_1_0 usb_1_1_6_1_1_0 usb_1_1_6_1_1_1 usb_1_1_6_1_1_2 usb_2_0_1_0 usb_2_1 usb_2_1_1_0 usb_usb1 usb_usb2
The issue is, you need to get libvirt name of the device and run the nodedev-detach - have you done that with no success?
If not, use some simple script such as (python)
import libvirt
conn = libvirt.openReadOnly() devices = conn.listAllDevices() for dev in devices: print dev.XMLDesc()
to easily find the device and use the <name> element for nodedev-detach call. That should handle unbinding it from the driver and possibly binding it to some usb stub if that exists. If that doesn't fix it, I admit that I'm not sure what could be the cause apart from OS/hw.
The xml injected is, I think right :
<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x0572'/> <product id='0x1321'/> </source> </hostdev>
Even with The device on the VM xml, the device does'nt appears in the Windows VM. Regards Alain

Hi, I've tried also to inject the device with virsh attach-device, all seems to work but nothing happen in the VM :
[root@unc-srv-hyp2 ~]$ virsh attach-device unc-srv-prnt3 usb-modem.xml Please enter your authentication name: root Please enter your password: Device attached successfully
What did I do wrong, any ideas ?
Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled.
Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt?
After that, try starting VM with hostdev element added to XML.

Hi,
Can you tell me if I can use an USB modem through one of the hypervisor hosts to a Windows VM ?
I’d like to install a Windows Fax Server.
Thank you for your answers.
should be possible using qemu args: -usbdevice host:vendor_id:product_id
in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:
<domain type='kvm'> <name>...</name> … <devices> … <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x@VENDOR@'/> <product id='0x@DEVICE@'/> </source> </hostdev> </devices> </domain>
if this option is not exposed in ui you can use vdsm-hooks[1] to modify the libvirt configuration and inject such device.
Regards, Alon

Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 2 Communications bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0572 Conexant Systems (Rockwell), Inc. idProduct 0x1321 bcdDevice 1.00 iManufacturer 1 Conexant iProduct 2 USB Modem iSerial 3 24680246 bNumConfigurations 2 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 73 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4
With nodedev we just see device nodes, pretty difficult to identify, even with --tree opt :
usb_1_0_1_0 usb_1_1 usb_1_1_1_0 usb_1_1_4 usb_1_1_4_1_0 usb_1_1_4_1_1 usb_1_1_6 usb_1_1_6_1 usb_1_1_6_1_0 usb_1_1_6_1_1_0 usb_1_1_6_1_1_1 usb_1_1_6_1_1_2 usb_2_0_1_0 usb_2_1 usb_2_1_1_0 usb_usb1 usb_usb2
The issue is, you need to get libvirt name of the device and run the nodedev-detach - have you done that with no success?
If not, use some simple script such as (python)
import libvirt
conn = libvirt.openReadOnly() devices = conn.listAllDevices() for dev in devices: print dev.XMLDesc()
to easily find the device and use the <name> element for nodedev-detach call. That should handle unbinding it from the driver and possibly binding it to some usb stub if that exists. If that doesn't fix it, I admit that I'm not sure what could be the cause apart from OS/hw.
The xml injected is, I think right :
<hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x0572'/> <product id='0x1321'/> </source> </hostdev>
Even with The device on the VM xml, the device does'nt appears in the Windows VM. Regards Alain

Hi, I've tried also to inject the device with virsh attach-device, all seems to work but nothing happen in the VM :
[root@unc-srv-hyp2 ~]$ virsh attach-device unc-srv-prnt3 usb-modem.xml Please enter your authentication name: root Please enter your password: Device attached successfully
What did I do wrong, any ideas ?
Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled.
Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt?
After that, try starting VM with hostdev element added to XML.

should be possible using qemu args: -usbdevice host:vendor_id:product_id
in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:
<domain type='kvm'> <name>...</name> … <devices> … <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x@VENDOR@'/> <product id='0x@DEVICE@'/> </source> </hostdev> </devices> </domain>
if this option is not exposed in ui you can use vdsm-hooks[1] to modify the libvirt configuration and inject such device.

I don't think that suspend vm somehow affect on power saving, because suspend vm not generate cpu load on host. So if you have two vms and two hosts, when you suspend vms, engine will shutdown all hosts(if HostsInReserve=0), so it can be good idea to set this parameter equal to 1, to have at least one host up if you need to run vms.

We have power saving policy that also have possibility to poweroff hosts(via power management), you can configure power saving policy parameters for you purpose(HighUtilization can have values from 50-100 and LowUtilization 0-49), so you can set LowUtilization=0 and HighUtilization=50, so load balancing will try migrate all vms on one host(if cpu utilization less that 50). And also you can set parameter "HostsInReserve" to 0 if you do not want additional hosts in reserve.

1) two servers powered on 2) operator suspend some virtual machines 3) load falls down 4) ovirt shutdown one server
Then operator unpauses virtual machines and ovirt starts again the 2nd server.

The powersaving policy is only applicable to the hosts, so if your low utilization threshold is below the power policy when you pause the vm, it should place the host into maintenance and migrate the paused vm (may cause problems).

I mean that I know that I can set a power saving policy, it is a very nice thing.
I need to be sure that I can pause/suspend (not shutdown) virtual machines.
I also need that, if I suspend enough virtual machines ovirt shutdowns server to save power following the power save policy.
Otherwise is it possible to manually shutdown a server forcing ovirt to migrate vms to the only one powered up?
Basically it is a "manual power saving" mode.

Thanks for reply. I just want now to be sure that you can pause vm and so trigger the low utilization parameter

We have power saving policy that also have possibility to poweroff hosts(via power management), you can configure power saving policy parameters for you purpose(HighUtilization can have values from 50-100 and LowUtilization 0-49), so you can set LowUtilization=0 and HighUtilization=50, so load balancing will try migrate all vms on one host(if cpu utilization less that 50). And also you can set parameter "HostsInReserve" to 0 if you do not want additional hosts in reserve.

Hello, I would like to ask if it is possible to do this use case with ovirt:
1) two servers powered on 2) operator suspend some virtual machines 3) load falls down 4) ovirt shutdown one server
Then operator unpauses virtual machines and ovirt starts again the 2nd server.
Thanks, Mario
