[libvirt] Fail to import available VM image
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

all the softwares are of latest version (libvirt 0.9.10 and virtinst-0.60.1) 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?

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!

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_star... If that ends up not being your problem, please reply to this message, but sending the reply to libvirt-users@redhat.com (I also Cc'ed this message there) rather than to libvir-list@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 is not enough. do i need a script to configure and start libvirtd properly for me? and it seems i must configure the virtual network somehow?
The "default" network should already be there as part of the stock install.

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? ok, i change the command a bit, and it went further. here is how i did:
(1) compiled everything from source, then install (make install) to my Ubuntu
(2) start libvirtd on commandline # libvirtd -d
(3) import my KVM image to libvirt
$ virt-install --connect qemu:///system -n winxp -r 800 --accelerate --vnc -v --noautoconsole --import -f /home/jun/img/img.winxp
it failed, and the log is like below:

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 :-).
this is not my problem, as i dont use dnsmasq. below is my /var/log/libvirt/libvirtd.log .... 2012-02-15 01:54:18.358+0000: 10580: info : libvirt version: 0.9.10 2012-02-15 01:54:18.358+0000: 10580: error : virCommandWait:2308 : internal error Child process (/sbin/iptables --table mangle --delete POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill) status unexpected: exit status 2 2012-02-15 01:54:18.367+0000: 10580: error : virCommandWait:2308 : internal error Child process (/sbin/iptables --table mangle --insert POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill) status unexpected: exit status 2 2012-02-15 01:54:18.367+0000: 10580: warning : networkAddGeneralIptablesRules:1301 : Could not add rule to fixup DHCP response checksums on network 'default'. 2012-02-15 01:54:18.367+0000: 10580: warning : networkAddGeneralIptablesRules:1302 : May need to update iptables package & kernel to support CHECKSUM rule. and currently output of "brctl show" is: # brctl show bridge name bridge id STP enabled interfaces pan0 8000.000000000000 no virbr0 8000.000000000000 yes so what is wrong with my system? thanks, Jun

and currently output of "brctl show" is: # brctl show bridge name bridge id STP enabled interfaces pan0 8000.000000000000 no virbr0 8000.000000000000 yes 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!

so what is wrong with my system?
