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.

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

Not really understand you, what you mean by "you can pause vm and so trigger the low
utilization parameter"?

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

Subject: [ovirt-users] USB Modem in a VM
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.

New subject: USB Modem in a VM
Hi,
Thank you for your answer, I've tried to insert my USB modem, but it doesn't up in
the Windows VM.
I've tried to insert via virt-manager without success, I can't apply the
modification, however I see the modem using lsusb :
lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID

I've unload the "cdc_acm" kernel module via rmmod without success.
I've also tried to edit the xml appending the ID and VENDDOR tags :
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x0572'/>
<product id='0x1321'/>
</source>
</hostdev>
Ut at the first load the config disappears...
Do I need to restart the host or restart libvirtd services ?
Thanks for your help

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,
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 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.

Subject: Re: [ovirt-users] USB Modem in a VM
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.

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_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

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>

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.

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 Martin,
That's what I've done, but the result is a missing argument.
[root@unc-srv-hyp2 ~]$ python2.6 usb_dev.py
Traceback (most recent call last):
File "usb_dev.py", line 4, in <module>
conn = libvirt.openReadOnly()
TypeError: openReadOnly() takes exactly 1 argument (0 given
My mistake, you can use openReadOnly(0) (can be omitted for some libvirt versions).

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.

New subject: USB Modem in a VM
I've replaced with openReadOnly(0), but had a "argument 1 must be string or None,
not int" issue, so I changed to None, but I had :
[root@unc-srv-hyp2 ~]$ python2.6 usb_dev.py
Traceback (most recent call last):
File "usb_dev.py", line 5, in <module>
devices = conn.listAllDevices()
TypeError: listAllDevices() takes exactly 2 arguments (1 given)
I put the VM name in openReadOnly("unc-srv-prnt3") and I had this issue :
libvirt: error : no connection driver available for unc-srv-prnt3
Traceback (most recent call last):
File "usb_dev.py", line 4, in <module>
conn = libvirt.openReadOnly("unc-srv-prnt3")
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 247, in
openReadOnly
if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')
libvirt.libvirtError: no connection driver available for unc-srv-prnt3
What's wrong ?

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.

Subject: RE: [ovirt-users] USB Modem in a VM
I've replaced with openReadOnly(0), but had a "argument 1 must be string or
None, not int" issue, so I changed to None, but I had :
[root@unc-srv-hyp2 ~]$ python2.6 usb_dev.py
Traceback (most recent call last):
File "usb_dev.py", line 5, in <module>
devices = conn.listAllDevices()
TypeError: listAllDevices() takes exactly 2 arguments (1 given)
I put the VM name in openReadOnly("unc-srv-prnt3") and I had this issue :
libvirt: error : no connection driver available for unc-srv-prnt3
Traceback (most recent call last):
File "usb_dev.py", line 4, in <module>
conn = libvirt.openReadOnly("unc-srv-prnt3")
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 247, in
openReadOnly
if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')
libvirt.libvirtError: no connection driver available for unc-srv-prnt3
What's wrong ?
Missing flags parameter again, which version of libvirt are you running?
openReadOnly(0) and listAllDevices(0) should be correct for your version,
sorry for that again.

My mistake, you can use openReadOnly(0) (can be omitted for some libvirt
versions).

Subject: RE: [ovirt-users] USB Modem in a VM
I've replaced with openReadOnly(0), but had a "argument 1 must be
string or None, not int" issue, so I changed to None, but I had :
[root@unc-srv-hyp2 ~]$ python2.6 usb_dev.py Traceback (most recent
call last):
File "usb_dev.py", line 5, in <module>
devices = conn.listAllDevices()
TypeError: listAllDevices() takes exactly 2 arguments (1 given)
I put the VM name in openReadOnly("unc-srv-prnt3") and I had this issue :
libvirt: error : no connection driver available for unc-srv-prnt3
Traceback (most recent call last):
File "usb_dev.py", line 4, in <module>
conn = libvirt.openReadOnly("unc-srv-prnt3")
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 247, in
openReadOnly
if ret is None:raise libvirtError('virConnectOpenReadOnly()
failed')
libvirt.libvirtError: no connection driver available for unc-srv-prnt3
What's wrong ?
Missing flags parameter again, which version of libvirt are you running?
openReadOnly(0) and listAllDevices(0) should be correct for your version,
sorry for that again.

My mistake, you can use openReadOnly(0) (can be omitted for some
libvirt versions).

Hi,
Thank you for your answer, I've tried to insert my USB modem, but it doesn't up

I've tried to insert via virt-manager without success, I can't apply the

I've unload the "cdc_acm" kernel module via rmmod without success.
I've also tried to edit the xml appending the ID and VENDDOR tags :
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x0572'/>
<product id='0x1321'/>
</source>
</hostdev>
Ut at the first load the config disappears...
Do I need to restart the host or restart libvirtd services ?
Thanks for your help

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.
Best regards

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,

We have power =

power management), you can configure power saving policy<br>> =
parameters for you purpose(HighUtilization can have values from 50-100 =

and<br>> HighUtilization=3D50, so load balancing will try migrate all =
