Fixed images are running fine with 128Mb RAM, nothing should be changed in Eucalyptus ? I think we should disable ureadahead in cloud images, doesn't make much sense in a system that will rarely be booted twice ? Opening a ureadahead task, maybe it shouldn't better adapt to the amount of RAM available ? ** Changed in: eucalyptus (Ubuntu Lucid) Status: Triaged = Invalid ** Also affects: ureadahead (Ubuntu) Importance: Undecided Status: New ** Changed in: vm-builder (Ubuntu Lucid) Milestone: None = lucid-alpha-3 ** Changed in: vm-builder (Ubuntu Lucid) Status: New = Confirmed -- default uec-image requires at least 300 M of RAM to run - m1.small and c1.medium not needed by default https://bugs.launchpad.net/bugs/499520 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

To be clear, the issue here is more than just accounting. When we boot an instance in UEC with 256M or less of memory, the OOM kicks in and the system is generally not in good shape. looking into this further, the big difference between karmic and lucid /proc/meminfo was 'LowFree'. On an ec2 instance with 2G memory, I saw: Karmic: 681616 Lucid: 552616 That lead me to suspect ureadahead. It turns out, that if I remove ureadahead from the instance, I can boot in 96M of memory under kvm. With ureadahead in the instance, I get OOM messages at 256M. One thing to note, is that this is a fresh first-boot of ec2 instance. ureadahead has never profiled before, and can't be expected to have. -- default uec-image requires at least 300 M of RAM to run - m1.small and c1.medium not needed by default https://bugs.launchpad.net/bugs/499520 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I'm elevating the eucalyptus task here to High (which might be a bit ambitious), but I'm also targeting at A3. I've been doing some scalability testing on my 5-node cluster, each node having 4GB of memory. I'm able to run up to 14 x 256MB guests per node. It would be nice to get a few more on there. Still, I think we should at least have a good look at our default instance sizes, and just review them if nothing else (perhaps just closing this bug). This is a task for the distro sprint next week. :-Dustin ** Changed in: eucalyptus (Ubuntu) Importance: Wishlist = High ** Changed in: eucalyptus (Ubuntu) Milestone: None = lucid-alpha-3 -- default uec-image requires at least 300 M of RAM to run - m1.small and c1.medium not needed by default https://bugs.launchpad.net/bugs/499520 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 499520] Re: default uec-image requires at least 300 M of RAM to run - m1.small and c1.medium not needed by default
Two different issues here: the inflation of the minimal RAM amount needed to run a lucid cloud image, and a redefinition of the default VM types to better reflect the default use case. I think it's important to keep the memory usage in our cloud images to a minimum if possible and 300Mb sounds quite large as a minimum to me. I'll open a vmbuilder task to track the first issue, even if it's likely not to be a vmbuilder issue, feel free to change the affected package when the cause is better defined. ** Changed in: eucalyptus (Ubuntu) Importance: Undecided = Wishlist ** Changed in: eucalyptus (Ubuntu) Status: New = Triaged ** Also affects: vm-builder (Ubuntu) Importance: Undecided Status: New ** Changed in: vm-builder (Ubuntu) Importance: Undecided = High ** Changed in: vm-builder (Ubuntu) Assignee: (unassigned) = Scott Moser (smoser) -- default uec-image requires at least 300 M of RAM to run - m1.small and c1.medium not needed by default https://bugs.launchpad.net/bugs/499520 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
