Re: [Xen-users] xm create: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. One more question.

Next question:-

eth0            8000.001c2596e32b       no              peth0


pan0            8000.000000000000       no


virbr0          8000.000000000000       yes
Presence virbr0 in report seems strange. Direct port  Xen 3.4.2  to F11
doesn''t install daemon
libvirtd ( bridge virbr0 ) , unless you wrote xen-3.4.2-(x).fc12.src.rpm 
yourself.

So , from where bridge virbr0 comes  ?Install Libvirt on F11 for KVM would mess
Xen 3.4.2 port .What reports ?

# rpm -qa |  grep xen
build xen from souce on F11 doesn''t change this output.
Boris.

I believe disk should be also fixed.

Hi Geoff, 

Thanks for prompt reply.  I have assigned correct interface. Please see below
for more detail,





[root@localhost
rules.d]# brctl show 

bridge name     bridge id               STP enabled     interfaces


eth0            8000.001c2596e32b       no              peth0


pan0            8000.000000000000       no


virbr0          8000.000000000000       yes


[root@localhost xen]# cat test|grep -i vif
vif = [ ''type=ioemu, bridge=eth0'' ]

root@localhost xen]# xm create test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.


Looking the xend.log, I can see that, vif  virtual interface device is created
and  for status it is waiting in dom0(backend side) for hotplug callback status
of device... for more details see below full xend.log,  I have highlighted vif
log details in red color just for better visibility...  Please guide me through
my installation.

Re: [Xen-users] xm create: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. One more question.

Hi Boris,

I have followed this blog for my xen setup,
http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/


See below for few installed rpms,
[root@localhost ~]# rpm -qa |  grep xen
xen-libs-3.3.1-11.fc11.i586
[root@localhost ~]# rpm -qa |grep libvirt
libvirt-python-0.6.2-19.fc11.i586
libvirt-0.6.2-19.fc11.i586
[root@localhost ~]# rpm -qa |grep bridg
bridge-utils-1.2-7.fc11.i586

Re: [Xen-users] xm create: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. One more question.

You did it wrong. I just ran it on my Xen 3.4.1 Dom0 (2.6.31.6 pvops)  on top of
F12 (F11 would show the same) :-

[root@fedora12sda ~]# rpm -qa|grep xen
xen-3.4.1-5.fc12.x86_64
xen-hypervisor-3.4.1-5.fc12.x86_64
xen-libs-3.4.1-5.fc12.x86_64
xen-runtime-3.4.1-5.fc12.x86_64

[root@fedora12sda ~]# rpm -qa|grep virt
virt-viewer-0.2.0-1.fc12.x86_64
virt-manager-0.8.0-7.fc12.noarch
libvirt-0.7.1-15.fc12.x86_64
libvirt-client-0.7.1-15.fc12.x86_64
libvirt-python-0.7.1-15.fc12.x86_64
python-virtinst-0.500.0-5.fc12.noarch

You need to install xen-3.4.1-5.fc12.src.rpm. Build xen packages via the most
recent xen-3.4.1-5.fc12.src.rpm. Install Xen Hypervisor ,then install libvirt.
Then install pvops kernel. Virt-install perform HVM DomU setup with no problems.
You shouldn''t
need regular xm-profile. However, standard HVM xm-profile would work fine as
well
if you pass through procedure properly

Boris.

Hi Boris, 

I have followed this blog for my xen setup, 
http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/


See below for few installed rpms, 
[root@localhost ~]# rpm -qa |  grep xen
xen-libs-3.3.1-11.fc11.i586
[root@localhost ~]# rpm -qa |grep libvirt
libvirt-python-0.6.2-19.fc11.i586
libvirt-0.6.2-19.fc11.i586

[root@localhost ~]# rpm -qa |grep bridg
bridge-utils-1.2-7.fc11.i586

virbr0          8000.000000000000       yes
Presence virbr0 in report seems strange. Direct port  Xen 3.4.2  to F11
doesn''t install daemon

libvirtd ( bridge virbr0 ) , unless you wrote xen-3.4.2-(x).fc12.src.rpm 
yourself.

So , from where bridge virbr0 comes  ?
Install Libvirt on F11 for KVM would mess Xen 3.4.2 port .What reports ?

# rpm -qa |  grep xen
build xen
 from souce on F11 doesn''t change this output.

I believe disk should be also fixed.

Remove vif and try to start HVM DomU.
What happens ?

Hi Geoff, 

Thanks for prompt reply.  I have assigned correct interface. Please see below
for more detail,



[root@localhost
rules.d]# brctl show 

bridge name     bridge id               STP enabled     interfaces



eth0            8000.001c2596e32b       no              peth0



pan0            8000.000000000000       no


virbr0          8000.000000000000       yes


[root@localhost xen]# cat test|grep -i vif
vif = [ ''type=ioemu, bridge=eth0'' ]

root@localhost xen]# xm create test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.



Looking the xend.log, I can see that, vif  virtual interface device is created
and  for status it is waiting in dom0(backend side) for hotplug callback status
of device... for more details see below full xend.log,  I have highlighted vif
log details in red color just for better visibility...  Please guide me through
my installation.
