hi,
i am trying to import an available KVM image to use with libvirt.
i am not sure if this is the problem of libvirt or not, so bear in me
if that is not the case.
i run the following command, and got error:
# virt-install -n winxp -r 800 -f img.winxp --accelerate --vnc
--noautoconsole -v --import
ERROR [Errno 10] No child processes
all the softwares are of latest version (libvirt 0.9.10 and virtinst-0.60.1)
where am i wrong?
many thanks,
Jun

It
works well with python-virtinst-0.600.0-5.el6 for me. if you may
attach your
.virtinst/virt-install.log, it should be helpful for debugging.

yes, below is the log content.
also, one thing i dont understand: why it says "Hypervisor name is
'vbox'" in the log? i dont specify any hypervisor name in my command,
and i want to use KVM for my image.
thanks.

Hi Jun,
I assume you haven't changed libvirt default URI, it may be a issue,
I want to know whether it works for you if you explicitly specify
--connect qemu:///system with virt-install? I think a root reason
probably is your disk image location, the log said it can't find
storage volume, if you put img.winp under the /var/lib/libvirt/images,
then give a disk absolute path to virt-install, Does it work for you?
Regards,
Alex

Hi Jun,
The log is very clear, you need a virtual network 'default' for libvirt default
bridge virbr0,
it should be your complication issue, the default case is 'virsh' locates in
/usr/bin/virsh,
and 'libvirtd' locates in /usr/sbin/libvirtd, if your 'virsh' and
'libvirtd' are put other
location, I guess you haven't used --prefix=/usr when run ./configure, or you also
haven't
directly used ./autogen.sh --system, if so, your 'default' virtual network
probably doesn't work.
so at first, you should make sure virtual network 'default' works well, you may
check it by
ifconfig and virsh net-list, for example:
# ifconfig virbr0
virbr0 Link encap:Ethernet HWaddr 52:54:00:38:FF:C4
inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:436 errors:0 dropped:0 overruns:0 frame:0
TX packets:1080 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:56435 (55.1 KiB) TX bytes:127958 (124.9 KiB)
# virsh net-list
Name State Autostart
-----------------------------------------
default active yes
# virsh net-dumpxml default
<network>
<name>default</name>
<uuid>40447e3e-4b09-44db-bc70-decef1189044</uuid>
<forward mode='nat'/>
<bridge name='virbr0' stp='on' delay='0' />
<mac address='52:54:00:38:FF:C4'/>
<ip address='192.168.122.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.122.2' end='192.168.122.254' />
</dhcp>
</ip>
</network>
At present, you may try to manually define and active 'default' virtual network,
and paste the above xml into /etc/libvirt/qemu/networks/default.xml then
virsh net-define /etc/libvirt/qemu/networks/default.xml and virsh net-create default,
if everything is okay you will see a active default network by virsh net-list, and
you also see a network bridge named 'virbr0' on host by ifconfig.
Finally, if virtual work works well, then you may try previous operations.
Good Luck!
Alex

A very common cause of this problem is that a systemwide instance of
dnsmasq is already (erroneously) listening on the bridge created by
libvirt for the default network. I took your email as an oppurtunity to
write an entry in the new Troubleshooting section of the libvirt wiki.
It will explain to you how to solve your problem (*if* this is your
problem, of course :-).
http://wiki.libvirt.org/page/Virtual_network_%27default%27_has_not_been_s...
If that ends up not being your problem, please reply to this message,
but sending the reply to libvirt-users(a)redhat.com (I also Cc'ed this
message there) rather than to libvir-list(a)redhat.com. (The former is the
official list for user questions about libvirt, whil libvir-list is
intended for for people discussing the code.)
i guess perhaps just starting "libvirtd -d" on commandline

and it seems i must configure the virtual network somehow?
The "default" network should already be there as part of the stock install.

A very common cause of this problem is that a systemwide instance of
dnsmasq is already (erroneously) listening on the bridge created by
libvirt for the default network.
Laine, yeah, I'm missing this important
reason.
I took your email as an oppurtunity to
write an entry in the new Troubleshooting section of the libvirt wiki.
It will explain to you how to solve your problem (*if* this is your
problem, of course :-).
http://wiki.libvirt.org/page/Virtual_network_%27default%27_has_not_been_s...
Great, I want to tidy up a doc about this ago, it should be very helpful
for a new guys.
Thanks & Regards,
Alex
If that ends up not being your problem, please reply to this
message,
but sending the reply to libvirt-users(a)redhat.com (I also Cc'ed this
message there) rather than to libvir-list(a)redhat.com. (The former is the
official list for user questions about libvirt, whil libvir-list is
intended for for people discussing the code.)

The "default" network should already be there as part of the stock install.

You means you haven't a dnsmasq
process is running before starting virtual
network 'default', right? I want to know a cmdline argument of the dnsmasq
process by ps -ef|grep dnsmasq
below is my /var/log/libvirt/libvirtd.log
....

If you manually stop virtual network
'default' and dnsmasq service then restart 'default'
network, does it work for you? for instance:
% virsh net-destroy default
% service dnsmasq status
if your dnsmasq is still active then stop it, otherwise, please ignore the following
step:
% service dnsmasq stop
make sure you haven't any dnsmasq process is running by ps -ef|grep dnsmasq, then
active 'default' network again:
% virsh net-start default
if the above step is failed, please give related logs and virsh output.
what's dnsmasq process with cmdline?
% ps -ef|grep dnsmasq
Good Luck!
Alex
so what is wrong with my system?
thanks,
Jun
