Description Julian Sikorski 2008-10-17 08:20:59 EDT
Created attachment 320656 [details] Screenshot showing where the rawhide installation stops Description of problem: As instructed in bug 454616, I am opening a new issue regarding this problem. Basically, I tried to install paravirt Fedora rawhide ii686 guest on a Fedora 9 x86_64 host. It is important to have xenner service running, otherwise one will hit bug 462120. The installation stops right at the beginning, showing "parallel0 console" (screenshot attached). Version-Release number of selected component (if applicable): libvirt-0.4.6-2.fc9.x86_64 xenner-0.46-1.fc9.x86_64 How reproducible: always Steps to Reproduce: 1. service xenner start 2. virt-install --paravirt --os-type=linux --location=http://sunsite.icm.edu.pl/pub/Linux/fedora/linux/development/i386/os/ --name=pararawhide-i386 --vcpus=1 --file=/var/lib/libvirt/images/pararawhide-i386.img --accelerate --ram=512 --file-size=15 2. wait until stuff gets downloaded Actual results: installation stops Expected results: one is able to complete the installation Additional info: Please let me know if any additional information is needed.
Comment 1 Julian Sikorski 2008-11-04 06:17:27 EST
Not sure how important that is, but if you answer no to the question about enabling graphics, install will stop saying no consoles are available.
Comment 2 Gerd Hoffmann 2008-11-04 06:49:03 EST
Can you attach /var/log/libvirt/qemu/pararawhide-i386.log please?
Comment 3 Julian Sikorski 2008-11-04 06:59:21 EST
Created attachment 322413 [details] Log file of an attempted install using virt-install, no graphics Here you go. This is the latest one, so I believe it contains data for installation without graphics support enabled.
Comment 4 Gerd Hoffmann 2008-11-04 07:10:22 EST
What is your xen-runtime version? Must be latest (3.2.0-15.fc9) with this fix: * Thu Jul 31 2008 Mark McLoughlin <email@example.com> - 3.2.0-15.fc9 - Support booting bzImage DomU kernel (e.g. Fedora 10)
Comment 5 Julian Sikorski 2008-11-04 07:13:23 EST
That's what I have installed here: [jsikorski@snowball dev]$ rpm -q xen-runtime xen-runtime-3.2.0-15.fc9.x86_64
Comment 6 Gerd Hoffmann 2008-11-04 07:30:28 EST
Hmm, thats odd, xen_guest_parse shouldn't fail then, and it actually works for me (64bit f9 host, f10-snap3 32bit guest). Can you run "xenner -debug 2 -kernel /path/to/vmlinuz-PAE" and attach the output please?
Comment 7 Julian Sikorski 2008-11-04 07:37:37 EST
I hope I used the correct path, it was the only vmlinuz-PAE I was able to find: [root@snowball jsikorski]# xenner -debug 2 -kernel http://sunsite.icm.edu.pl/pub/Linux/fedora/linux/development/i386/os/images/pxeboot/vmlinuz-PAE [xenner,2] started as: "xenner" "-debug" "2" "-kernel" "http://sunsite.icm.edu.pl/pub/Linux/fedora/linux/development/i386/os/images/pxeboot/vmlinuz-PAE" kvm capability clocksource: not enabled kvm capability nop-iodelay: not enabled kvm capability mmu-op: not enabled [xenner,2] prepare_environment: LD_LIBRARY_PATH=/usr/lib64/xenner [xenner,2] do_fork_exec: "/usr/lib64/xen/bin/qemu-dm" "-M" "xenpv" "-d" "4584" "-domain-name" "no-name" "-nographic" "-serial" "stdio" "-net" "none" domid: 4584 Console: prepared domain, waiting for ringref at /local/domain/4584/console or /local/domain/4584/serial/0 FB: Waiting for KBD backend creation Doing backend watch on /local/domain/0/backend/vkbd/4584/0 Wrong state 0 FB: Shutting down backend ==================== setup ==================== libxc: xc_evtchn_open -> handle 9 libxc: xenner_evtchnd_domid(handle 9, domid 4584) -> 4584 libxc: xc_evtchn_bind_unbound_port(handle 9, domid 0) -> 1 [xenner,2] evtchn_port: port 1 is xenstore libxc: xc_evtchn_bind_unbound_port(handle 9, domid 0) -> 2 [xenner,2] evtchn_port: port 2 is console xc_dom_allocate: cmdline="(null)", features="(null)" xen_guest_parse: ----- parse kernel ----- xc_dom_kernel_file: filename="http://sunsite.icm.edu.pl/pub/Linux/fedora/linux/development/i386/os/images/pxeboot/vmlinuz-PAE" xen_guest_parse: ----- FAILURE ----- domain_builder: ----- FAILURE ----- domain builder failed xenner_cleanup: ----- cleaning up ----- [root@snowball jsikorski]#
Comment 8 Gerd Hoffmann 2008-11-04 07:45:17 EST
-kernel arg must be a local file
Comment 9 Julian Sikorski 2008-11-04 07:55:49 EST
Created attachment 322415 [details] Output of xenner command I did something clueless: downloaded the file from the url and saved it on the hard drive, then I ran the suggested xen command. It ended up spitting out libxc: xc_evtchn_notify(handle 9, port 2) -> 0 until killed with ctrl-c. Does it mean that paravirt installs from network are unsupported?
Comment 10 Gerd Hoffmann 2008-11-04 08:03:16 EST
Back to square one. Parsing the guest kernel worked fine this time, thus the logfile from comment #3 is probably stale. Can you retry the install and attach a fresh logfile? Network installs are supported. xenner doesn't fetch the kernel itself though, virt-install handles that.
Comment 11 Julian Sikorski 2008-11-04 08:26:28 EST
Created attachment 322421 [details] Log file of an attempted install using virt-install, no graphics It must have been stale, sorry. Here is the console output: [root@snowball qemu]# LANG=C virt-install --paravirt --os-type=linux --location=http://sunsite.icm.edu.pl/pub/Linux/fedora/linux/development/i386/os/ --name=pararawhide-i386 --vcpus=1 --file=/var/lib/libvirt/images/pararawhide-i386.img --accelerate --ram=512 --file-size=15 Would you like to enable graphics support? (yes or no) no Starting install...

You can reconnect to the console to complete the installation process. [root@snowball qemu]# After that the domain was still running, virt-manager said it was not configured for a guest and I had to destroy it.
Comment 12 Julian Sikorski 2008-11-04 08:34:08 EST
Created attachment 322423 [details] Log file of an attempted install using virt-install, with graphics Same file, but this time with graphics support enabled. Sits displaying parallel0 console indefinitely.
Comment 13 Gerd Hoffmann 2008-11-04 08:59:11 EST
Uhm, virt-install creates a pretty pointless configuration. There isn't a serial line configured. IMHO it should do that. Especially for the non-graphical install ... Ok, try fixing it up this way: (1) start install as in comment #11 (2) virsh dumpxml <domain> > tmp.xml (3) virsh destroy <domain> (4) edit tmp.xml, add "<serial/>" to the devices. (5) virsh define tmp.xml (6) virsh start <domain> && virsh console <domain> Best case would be it works now. Even if it doesn't work we should at least see the kernel boot messages, giving clue what is going wrong.
Comment 14 Julian Sikorski 2008-11-04 13:45:01 EST
Created attachment 322467 [details] edited tmp.xml [root@snowball jsikorski]# LANG=C virsh start pararawhide-i386 && virsh console pararawhide-i386 Domain pararawhide-i386 started unable to open TTY /dev/pts/2: No such file or directory [root@snowball jsikorski]#
Comment 15 Gerd Hoffmann 2008-11-05 04:31:37 EST
Hmm, what does "virsh list" say then? Does the guest still run? Could be virt-install cleaned up and deleted the kernel fetched from the internet, so the kernel path in the xml file doesn't work any more. Try fetching kernel & initrd by hand then and put the locations into the xml file.
Comment 16 Julian Sikorski 2008-11-05 05:06:53 EST
initrd & kernel were indeed deleted, so I downloaded them manually. Now the domain shows up in virsh list, but the error is only slightly different: /dev/pts/2 is replaced with /dev/pts/4.
Comment 17 Gerd Hoffmann 2008-11-06 06:36:09 EST
Hmm. No clue. Can you attach the libvirt logfile for this attempt please?
Comment 18 Julian Sikorski 2008-11-06 13:40:54 EST
Created attachment 322769 [details] Log file of domain defined with tmp.xml Does not look much different...
Comment 19 Julian Sikorski 2008-11-06 13:41:34 EST
Created attachment 322770 [details] xml file used to define the above domain
Comment 20 Gerd Hoffmann 2008-11-07 03:20:11 EST
[xenner,1] child 8466 (qemu-dm) exited: 1 Thats why /dev/pts/4 disappeared, qemu-dm handles it and it is gone (probably crashed). Ok, one more experiment: can you try adding <graphics> to the devices? That could work around qemu-dm crash. Also add "console=hvc0" to the command line then, otherwise the kernel will prefer the framebuffer. There is also this one in the log: [xenner,1] qemu_disk_config_blkbackd: if != xen, ignoring disk Can you change the bus='ide' to bus='xen' in the xml config? Otherwise the guest will have no disk. Thanks.
Comment 21 Julian Sikorski 2008-11-07 10:01:19 EST
Created attachment 322859 [details] xml that made it work With the above file anaconda started and reached the stage after connection type selection. Is that good enough?
Comment 22 Julian Sikorski 2008-11-07 10:02:46 EST
Created attachment 322860 [details] log of the above attempt
Comment 23 Julian Sikorski 2008-11-07 10:03:31 EST
It should be noted that anaconda got stuck after that, but it's an improvement nontheless.
Comment 24 Julian Sikorski 2008-11-12 05:14:33 EST
Oops, looks like it works perfectly fine now, sorry. The installer was getting stuck at the point in which it was supposed to fetch install.img due to bug #467687. Once I realised that, I restarted the virtual network and install.img is being retrieved as we speak.
Comment 25 Julian Sikorski 2008-11-22 05:24:53 EST
Do you want me to do any more testing? Fedora 10 is about to be released, and it won't be long until I update to it. It is likely I won't be able to reproduce the issue any more then.
Comment 26 Julian Sikorski 2008-12-12 11:01:07 EST
Seems like it works in Fedora 10.
