[ovirt-users] Put the engine inside hosts after installation
Hello, I would like to try ovirt with hosted engine installation. I had so many problems (I have written them in another thread) so I will not try anymore hosted installation (up and running with ovirt 3.5 tutorial) But now I would try this approach: I install the engine on a dedicated server or as a virtual machine in another kvm based virtualizator. Now I create an ovirt cluster and use it. Can I after that install change my mind and so move the engine as a vm in the cluster? Or can I install a new engine in the cluster and powerdown the first engine? Thanks in advance for help, Mario ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[ovirt-users] Low cost fencing/stonith devices
Hello, I ask this question again to see if there are some improvements. I am searching for a low cost stonith/fencing device for servers or hardware that has no ipmi/ilo on board. I see that there are some interesting products on the market like ubnt/mfi mpower that are controllable power outlets but there is no driver for them. In my use case WOL support will be enough (using it with ssh or shared storage fencing) but as far as I know WOL is not yet supported in ovirt. So is there some fencing device supported in 100/200$ price range? Thanks, Mario ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Ok I will wait 3.5.1 and try again. Great, please help us reporting any other issue or strange thing. Keep present that hosted-engine also installs and configures ovirt-hosted-engine-ha daemon to ensure HA capabilities restarting the engine VM if the host witch runs the VM goes down. In the setup you are proposing you are loosing that capability. I supposed the ha capability was offered by ovirt cluster. I need to investigate. HA capability is provided for other VMs by oVirt engine. But who provide it if the engine itself is on a VM on the host that it's managing? HA for the Engine VM needs to be managed by the hosts and not the Engine itself: so we have ovirt-hosted-engine-ha that ensure HA for the engine VM, the engine cloud than provide HA for other VMs. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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)

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.

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

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

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.

Re: [ovirt-users] Low cost fencing/stonith devices
Hello Mario, great you ask that, I am pretty interested myself. On 16.01.2015 12:31, Mario Giammarco wrote: Hello, I ask this question again to see if there are some improvements. I am searching for a low cost stonith/fencing device for servers or hardware that has no ipmi/ilo on board. I see that there are some interesting products on the market like ubnt/mfi mpower that are controllable power outlets but there is no driver for them. In my use case WOL support will be enough (using it with ssh or shared storage fencing) but as far as I know WOL is not yet supported in ovirt. Please see [1] - I enclose Martin: What is the status of the Future Enhancements WOL; or better what needs to be done and how can we help? I think we need a custom fence agent here, WOL in python is easily done [3] and the MAC filed could be mapped to one of the configurable items. Though I find it harder working with the fence_agent concept itself. Atm, I did not have time to persue this subjct any futher. So is there some fencing device supported in 100/200$ price range? One option would be networked PDU's [2] (here in Germany, they are around 200 Euro), maybe you can get some used ones. I think there is a list with supported devices though I cannot find it ATM. If I get it correctly the idea would be to define the outlet as Power Management, and switch it on via PMP. Configure the hosts to boot at power restore. The host would be shutdown via SSH anyway; the PM device only used for start up.

[ovirt-users] Use dedicated I/O service domain in KVM
Hi, I want to use a dedicated guest VM to handle I/O request just as I/O service domain used in xen. Specifically, using network I/O as an example, I should directly assign the NIC to one guest VM (using pci-assign option), after that all other guest VMs should perform network I/O through that VM rather than the host OS. Is there currently any viable approach to do this? If not, I want to implement one. Currently I'm thinking of combining nahanni shared memory and vhost architecture to implement it, is there any other suggestions? Thanks for any help. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Unfortunately having a complete list of hardware supported is not so easy. And because they are power devices each country has its standard. Infact now I am searching on ebay switched rackmount pdu and I find only item from english shops (that costs more than 200 euro). Can you please tell me the german translation of switched rackmount pdu so I can search in german shops?

Re: [ovirt-users] Put the engine inside hosts after installation
2015-01-16 12:37 GMT+01:00 Simone Tiraboschi stira...@redhat.com: HA capability is provided for other VMs by oVirt engine. But who provide it if the engine itself is on a VM on the host that it's managing? HA for the Engine VM needs to be managed by the hosts and not the Engine itself: so we have ovirt-hosted-engine-ha that ensure HA for the engine VM, the engine cloud than provide HA for other VMs. I am surprised. I supposed that HA was self provided by the cluster like in xenserver. So you tell me that is the engine that checks if servers and vms are on like in cloudstack? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
