[Bug 1039405] Re: Lockups when running vm's with 768MB of memory

[Colin Watson]

I use 768MB for all my installer test VMs, and it's not that long since
I bumped that up from 512MB; so there is something else wrong here, and
I don't think simply giving up and pre-emptively refusing to install
with 768MB is the right answer here.

Title:
  Lockups when running vm's with 768MB of memory

Status in “ubiquity” package in Ubuntu:
  New
Status in “ubiquity” source package in Precise:
  New

Bug description:
  version tested:  ubiquity 2.10.20 on 12.04.1 daily build.
  $md5sum precise-desktop-amd64.iso
  64cae667e6fde29ea86043ede5e79493  precise-desktop-amd64.iso

  Reproducing:
  setup a new KVM machine with 768 MB of ram.  (because users were reporting crashes with 768)

  *after booting, select try Ubuntu
  * start the installer, but not anything else.
  * select "something else"
  since the disk has no parition table, click to create a "new partition table
  create an 888 megabyte swap at the end of the disk
  create a 7701 M swap at the beginning of the disk.
  Ubiquity crashes when clicking to the next screen.

  you'll notice that the syslog has a: OSError: [Errno 12] Cannot
  allocate memory.

  To fix this bug, ubiquity should not be installing on PC's with too little RAM, especially when crashes are so consistent.
  Ubiquity should CLEARLY warn about crashes on low-ram machines.  

  here's the syslog and other stuff:
  x at ubu:~$ pastebinit debug
  http://paste.ubuntu.com/1158548/
  x at ubu:~$ pastebinit partman
  http://paste.ubuntu.com/1158549/
  x at ubu:~$ pastebinit syslog
  http://paste.ubuntu.com/1158550/
  x at ubu:~$ pastebinit version
  http://paste.ubuntu.com/1158551/
  x at ubu:~$ cat version
  ubiquity 2.10.20
