I tried this workaround, at point 4, instead of waiting, switch to another vt. Then tail -f packaging.log. I tried this two times, with different results. The first time, the dependencies were resolved, i switched back to anaconda, but anaconda was heavily wounded, sluggish, i tried to access 'software selection' again and got the 'aberrant snapshot' below. Of course, anaconda has slowed and became stalled. The second time, anaconda never finished resolving dependencies, i ctr+c the running tail and noticed the guest had become sluggish... Top shows process loop1 is always using a minimum of 63% (to 100%) cpu time. I switch back to anaconda, but evidently the guest is kaput... So, the common factor is something eating the cpu.

the 'aberrant snapshot' of the guest, reboot is needed
I'm not seeing any sluggishness here. How much memory do you have in the system in question? Created attachment 624121 [details]
btrfs-3 guest (qemu xml)
The guest has 768mb ram.
I will try with 2048 and post an update shortly.
I tried this: 2048MB -> OK (Reproduced 0 times out of 2 tries) 1024MB -> OK (Reproduced 0 times out of 2 tries) 768MB -> BAD (Reproduced 2 times out of 2 tries) It seems that 768mb is not enough. Is currently expected for anaconda to display a warning / error dialog if the amount of memory is less than the official value? We don't at this time have a good idea as to what the memory requirements are. A lot of it also has to do with your boot and install method. How was this system booted, where was stage2 loaded from? "How was this system booted, where was stage2 loaded from?" Using KVM/SPICE(QLX), boot from cdrom, selecting the option "install/upgrade fedora". "We don't at this time have a good idea as to what the memory requirements are. A lot of it also has to do with your boot and install method." Ok, but is it there some target value for the minimum ram anaconda need? (even if it is provisional). I believe that beta should be released with a known memory requirement. (at least to setup the testing guests correctly). At least in this specific case, 768mb seems to be not enough. Well, I would hope that when booting from CDrom, thus loading stage2 from there instead of downloading it into ram, and using an install source on the media rather than again downloading it to disk we could manage to install graphically a system with only 768 megs of ram. If we cant, I would consider that a bug somewhere. Finding that and fixing that bug may be very difficult, but I do believe it would be a bug. Currently this bug-report shows that there is at least one example of anaconda needing 1gb. Certainly 768mb were enough for most common scenarios, and that is good. 1- Anaconda 'hard memory requirement' (HARD_MEM_REQ) * Will print an error and prevent installing. (instead of behaving erratically due to low memory conditions). No bug-reports are wanted with such ram-size. * Installing from DVD as a source (at a minimum) must work within this limit. >> Currently it is set to 512Mb (there is an error in text mode, wich informs the user that it has not enough RAM) 2- Anaconda 'soft memory requirement' (SOFT_MEM_REQ) * Anaconda will not prevent installing, it will print a warning instead: "You have less than SOFT_MEM_REQ of RAM, some features might not work or might work incorrectly/erratically. Please try with more RAM first before filling a bug-report" >> Not sure if anaconda supports this, but currently any ram-size less than 1GB should print a warning. This is mostly to improve bug-reporting. I repeated the test with F18b TC3 and it fails the same with 768mb and works with 1Gb. I repeated the test with F18b TC6 and it fails the same with 768mb I repeated the test with F18 RC2 (18.37.11) and it fails the same with 768mb This probably should be added to the release notes. This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
