[libvirt] Error in virt-install
Hi, I've just installed an centos 5.2 with all the updates 'till now. Next i've tried the following install script that worked fine: virt-install -n test -r 512 --vnc --file=/dev/VolGroup00/test-os -- location=ftp://mirrors/centos/5/os/i386 -x 'text' Next i've rebuild rpm of libvirt to libvirt-0.6.1 (using --with-rhel5-api). The rpm build fine and installed without any errors. Next i've retried the virt-install script but i get the following error: [root@localhost ~]# virt-install -n test -r 512 --vnc -- file=/dev/VolGroup00/test-os --location=ftp://mirrors/centos/5/os/i386

If i use a file as the target (instead of a block device) it also works: virt-install -n test -r 512 --vnc --file=/tmp/test-os --file-size=2 -- location=ftp://mirrors/centos/5/os/i386 Any ideas? Thanks, Nuno Fernandes
Ahh ... and if i run the virt-install in valgrind it works... Best regards, Nuno Fernandes On Friday 06 March 2009 17:21:25 Nuno Fernandes wrote:
Hi,
I've just installed an centos 5.2 with all the updates 'till now. Next i've tried the following install script that worked fine:
virt-install -n test -r 512 --vnc --file=/dev/VolGroup00/test-os -- location=ftp://mirrors/centos/5/os/i386 -x 'text'
Next i've rebuild rpm of libvirt to libvirt-0.6.1 (using --with-rhel5-api). The rpm build fine and installed without any errors. Next i've retried the virt-install script but i get the following error:
[root@localhost ~]# virt-install -n test -r 512 --vnc -- file=/dev/VolGroup00/test-os --location=ftp://mirrors/centos/5/os/i386 -x 'text'

I've memtested the memory and its fine. If i use a file as the target (instead of a block device) it also works:
virt-install -n test -r 512 --vnc --file=/tmp/test-os --file-size=2 -- location=ftp://mirrors/centos/5/os/i386
Any ideas?
Thanks, Nuno Fernandes

Hi,
I've just installed an centos 5.2 with all the updates 'till now. Next i've tried the following install script that worked fine:

Next i've rebuild rpm of libvirt to libvirt-0.6.1 (using --with-rhel5-api). The rpm build fine and installed without any errors. Next i've retried the virt-install script but i get the following error:

I guess the key is to run under GDB with -debuginfo installed so we get a complete stack trace - the 2 missing symbols between virDomainLookupByUUID and virFree will be the key to finding this...

I guess I nailed it down, it's something we introduced when converting memory allocation, and since the block getting allocated includes both char * and char we failed to allocate enough space for the leading char * array. With this patch I was able to create a new guest and have it load with virt-install (but just in serial concole, graphics didn't work for some reason), it disapeared from the domain list too after being restarted at the end of the installation, so there is more stuff to be fixed on RHEL/Centos Xen, but that one seems solved, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Ahhh, wow that was confusing :-) I didn't notice the one allocation covered the string array, and the strings themselves ! Probably worth a comment on the funtion that the strings should not be freed separately ACK

Yes, at this point it has tried to start 'virt-viewer' to show you the VNC console to complete installation. The fact that it couldn't start it was not a serious problem - you could easily start it yourself as you discovered. If you wanted to supress the error, you could pass the --noautoconsole flag to virt-install, which stops it trying to launch virt-viewer at all.
I access the console using vnc but as you said, after the instalation completes it didn't restart. It disappeared from "virsh list" but i'm able to start it again using:
[root@localhost ~]# virsh start test Domain test started [root@localhost ~]# virsh list Id Name State ---------------------------------- 0 Domain-0 running 3 test idle
If there's anything i can do to help please let me know.
This is actually the expected behaviour. Since virt-viewer could not be started directly, virt-install finished leaving you to manually restart the guest once installation was complete. If virt-install had been able to launch virt-viewer, it would have automatically restarted the guest once install was complete.
