[PLUGIN DEPRECATED] VM Manager (2015.02.24)

[dmacias]

 

 

 

I setup my spare USB flash drive with a fresh copy of unRAID 6b12 and the latest Virtman and KVM Manager. The create VM tab doesn't seem to setup VM's properly. It creates the sub-folder and qcow2 image but doesn't actually create the VM as there are no VM's listed under the Virtual Machines tab after clicking the Create VM button.

 

 

Here is my error:

 

Warning: libvirt_domain_create_xml(): internal error: early end of file from monitor: possible problem: 2014-12-25T04:32:52.796650Z qemu-system-x86_64: -device ide-cd,bus=ide.1,unit=1,drive=drive-ide0-1-1,id=ide0-1-1: Can't create IDE unit 1, bus supports only 1 units 2014-12-25T04:32:52.796671Z qemu-system-x86_64: -device ide-cd,bus=ide.1,unit=1,drive=drive-ide0-1-1,id=ide0-1-1: Device initialization failed. 2014-12-25T04:32:52.796679Z qemu-system-x86_64: -device ide-cd,bus=ide.1,unit=1,drive=drive-ide0-1-1,id=ide0-1-1: Device 'ide-cd' could not be initialized in /usr/local/emhttp/plugins/dynamix.kvm.manager/classes/libvirt.php on line 173

 

I've tried several times using different iso files and locations.

Which of your systems is this on?  Can you give me an example of a working config? Did you get an error with a name only? Maybe I can specify the bus in the create xml.

 

No, I didn't get an error with a name only when creating a vm. Here is a screenshot of my info using the create vm tab that throws the error. This is a working xml config with Windows 10 and GPU, mouse, and keyboard pass-through.

Ok got it. Thanks. No ide for q35.

Cool. I'll try again after you post an update to the plugin.

Cool. I'll try again after you post an update to the plugin.

I added the following to q35 machine xml so usb tablet works and changed ide to sata for cdroms.  Let me know if there's more I need to add as default.

<controller type='usb' index='0' model='ich9-ehci1'/>
<controller type='usb' index='0' model='ich9-uhci1'/>

Hi !

 

You can compare a default q35 machine generated from Virtual Machine Manager ( see link below), I think it's more to change .....

Thanks peter.  Most of the xml is generated by libvirt in virt-manager and this plugin. I just need to compare what's missing if anything and if what's missing matters. Like serial ports or ide or something else that is not needed. Like maybe I need more usb ports.

 

I have started adding hyperv tags for windows also.

[peter_sm]

I updated the plugin, I saw a settings tab, what would that be for? Can we delete the libvirt plugin?

 

Nice work anyway !

[barakthecat]

 

Your welcome and I appreciate the feedback.  The errors display where ever they occur on they page. That's why error reporting/debugging is off by default and the errors I can collect are displayed on the bottom of the page.

 

If something gets removed from the xml automatically then check your syntax. The plugin had nothing to do with that. Libvirt will remove bad code.

 

Which old plugin do you mean?

 

I mean the Web Virtual Manager that you posted before writing the VM Manager.

 

What's the proper syntax for adding a VNC password? when I enter <graphics type='vnc' port='5900' autoport='yes' passwd='YOUR-PASSWORD-HERE' websocket='5700' listen='0.0.0.0'> the passwd segment doesn't get saved.

For now settings is to enable debugging and add default iso and existing image locations. And control libvirt. Still need virtman plugin. Hopefully soon. 

 

Removing virtman plugin will require some effort though. Domain images will all need to be in their own folder with an image file, cfg file for autostart and the xml. They want it similar to xenman plugin.

You have it right and I it gets saved but for some reason the php libvirt_domain_get_xml_desc doesn't show it. Maybe it's a feature . However virsh edit domain_name does show the password. Have you tried connecting with a vnc client after saving the xml with the password in the plugin?

My issue is resolved. I've been able to create several VM's just fine.

 

Thanks again.

Amazing work on the plugin! (using Current Version: 2014.12.27a)

 

Really enjoying running Win8.1 as a guest.

 

Just tried to increase the disk capacity of the VM disk. Changed the size within KVM tab and receive the message

 

"you have uncommitted form changes"

 

I did not see how to save or commit changes. And when I restarted the VM the disk size was unchanged in the KVM tab.

 

Edit.

 

entered the new disk size, hit enter and there was a message saying that the disk had been resized. However when I checked this using

 

qemu-img info

 

it was still the same size. The KVM tab is also still showing it as the same size.

You can turn off debugging in settings.  But that error is from get disk stats function and it can't access the disk.  Either the path or permissions.

I was able to succesfully resize using

 

qemu-img resize filename.qcow2 +20G

 

from within the folder where the image resides.

It works until I restart the VM, then it seems to lose the password. I'll play around with it some more.

I notice that when I try to create a VM the only options for OS seem to be Windows and Linux.  What should be selected if I am interested if I want a different OS (e.g. Mac OS)?

The second option says Linux/OSX.  If there are some specific tweaks for OSX I can add them and a separate selection.  But really the windows option just enables hyperv tweaks, adds option for temporary drivers cdrom and disables the ability for 9p sharing.

[barakthecat]

If you want to run a Mac VM, be sure to follow the guide archdraft has put together. http://lime-technology.com/forum/index.php?topic=34864

In truth, it should say "Windows" or "Other."  There are other operating systems out there that aren't based on the NT/Linux kernel and they WILL virtualize fine under KVM.  Windows is just the only one (that I know of) that has special extension support which is where the Hyper-V settings come into play.

 

Important note:  if passing through an nVIDIA GPU, do NOT select Windows as the VM type, even if it is.  The Hyper-V extensions are detected by nVIDIA and will prohibit GPU pass through from working properly.

Hmm, this must be why I'm having so much trouble attempting to recreate a fresh windows 8 VM with my nvidia graphics. Do you happen to have a Windows 8 template you recommend using with nvidia?

Here is the XML from my Windows 8.1 VM where I have my GTX 780 passed through (along with several other devices ;-).

Just an FYI, I know there is a "hypervtimer" in there, but that isn't actually a viridian hyper-v extension, so its ok to keep that there.

[sparklyballs]

Tried creating a VM, got the install ubuntu normal screen through VNC , saw that i hadn't set MAC address so DHCP wasn't working.

 

tried stopping the VM and it wouldn't stop, so tried stopping libvirt via the webui, it stopped.

 

hit start again and it's been sitting here for 30 minutes and i'm locked out of the webui completely.

 

[sparklyballs]

RE my last post.

 

Not sure if it's a bug or something firefox related, but if i close the browser completely and open a new instance i can then get the webui and libvirt is running.

[jonp]

For future reference, there is a force shutdown button you can use to forcibly shut down a VM without resorting to stopping libvirt.
