I am trying to attach a usb device to my virtualbox node using libvirt. My node is already running, I stop my node and then I am trying to add this usb device.
I have a separate xml file defined for usb. It looks like this:
<hostdev mode='subsystem' type='usb'>
I am trying to attach it using code:
conn = libvirt.open("vbox:///session")
if conn ==None:
print 'Failed to open connection to the hypervisor'
print 'connected to vbox hypervisor driver'
domainInstance = conn.lookupByName('SampleNode')
filed = open('/root/testFolder/usbSharedFolder.xml', 'r')
config_str = filed.read()
When it is executed I am getting an error message saying:
libvir: VirtualBox Driver error : out of memory
Even with virsh it is giving the same error. I am using the below command:
attach-device SampleNode /root/testFolder/usbSharedFolder.xml
Can anyone tell me what is going wrong. It is really very important. Please do reply.
Thanks in advance.
