I see virtio functions in those traces. So am I right to assume that those installations were done in a KVM environment? Which version of the kernel are we looking at?

C de-Avillez (hggdh2) wrote :

@Stefan: yes, they are run on a KVM, under libvirt/qemu Natty. ON the host, these are the versions:

ii libvirt-bin 0.8.8-1ubuntu6 the programs for the libvirt library
ii libvirt0 0.8.8-1ubuntu6 library for interfacing with different virtualization systems
ii linux-image-2.6.38-8-server 2.6.38-8.42 Linux kernel image for version 2.6.38 on x86_64
ii linux-image-server 2.6.38.8.22 Linux kernel image on Server Equipment.
ii qemu-common 0.14.0+noroms-0ubuntu4.1 qemu common functionality (bios, documentation, etc)
ii qemu-kvm 0.14.0+noroms-0ubuntu4.1 Full virtualization on i386 and amd64 hardware

For the virtual machines: they were running Oneiric and linux-image-2.6.39-3-generic-pae.

Stefan Bader (smb) wrote :

Ok, thanks Carlos. So what we see in the guest logs is that the virtual network interface seems to try allocating a 128K receive buffer which fails and that triggers some OOM actions resulting in bad things. If I see this right, there seems to be 439M of memory available (probably set up as 512M and the rest lacking for page tables and so on).
Generally virnet is claimed to be able to really have a hard impact on memory (especially if there is any service doing transfers between host and guest) as transport is not limited by any transmission speed. Is there something configured like that.
The system can be tweaked a bit by telling it to try having more memory in reserve (/proc/sys/vm/min_free_kbytes) but I am not sure this is easily implemented for install. Would things improve by just allocating the guests more memory (768M, 1024M)?

I had this crash very regularly while testing i386 alternate images on VMs running on amd64 (kernel 3.0-1.2-generic 3.0.0-rc3). After increasing VM's memory it didn't happened in 4 runs.

We'll wait for tomorrows run and see if it happens when the test server is loaded.

Also, I've never seen this crash when running amd64 guest on an amd64 host on same hardware and same VM configuration. So it shouldn't happen anyway.

Looking at the whole thing more in depth, this turns out to be a very very very long winded way of the kernel telling us that something tried to allocate 128K of continuous memory and failed (which includes a stack trace and a dump of memory info). It does not say OOPS actually.
As far as I see this is likely triggered by virtnet_poll() which tries to pull in data from the virtual network. It does so using GFP_ATOMIC which allows for failure without waiting but does not automatically set the flag to suppress warnings like this. Probably that might be improved. The code AFAICS is prepared to handle the allocation failure and there does not seem to be an immediate crash involved.
In this report there is one statement about a hung installation. In the other confirmations I have not seen indication whether the install proceeds or not. There is not much more I can say from the posted messages. And the jenkins links seem to go to 404 for me.

Usually -- meaning on these installs I followed on Jenkins, and on my KVM tests -- the installation stalls. On Jenkins, the test eventually times out and fails (these were the Jenkins failed tests). On personal KVM runs I can see the progress bar stopping; I would then go into another console, and start killing some installation processes, and sometimes I killed the right one, and installation proceeded; sometimes I would completely bork the install.

If possible it would be good to have the syslog from such a failed installation. As said, the links above do not work and I was not able to get data any other ways. The allocation failure may just be an indication that we have some memory pressure. Would it be possible to add any debugging script(s) easily, if the syslog is not sufficiently providing data?

C de-Avillez (hggdh2) wrote :

Here you go. Note that this is the Debian-Installer syslog (the only syslog available on an install that I know of).

Stefan Bader (smb) wrote :

Thanks. So from this log I see several times that some allocations failed (order 2 to 4). I am not sure this log was from a run that went through. At least there did not seem to be any other indication of problems. And the failures first became worse (smaller allocations failing) but then recovered. So it goes with the assumption that the message itself is not fatal.
Generally it might be just of taxing the system hardly. The system has not much memory, the virtio net is performing well (better than an emulated card would), but the disk is probably not (running through an emulated IDE controller) and could be backed by a non-raw image, which would impact performance further.
Still this should not hang. Just be slow and maybe show messages about processes not getting scheduled. The problem will be to find any way to get something useful out of this...

Can this be confirmed with the beta release? Also, at the moment I do not see a strong hint about what the problem could be. Do we have a chance to set up those installs to write console output to a file? Then maybe add debug to the kernel command line in order to send even lower prio messages there.
I have not been able, yet, to get the same locally. Would it be possible to summarize a bit more details about the host and guest setup? What release is running on the host, beyond memory what is the exact guest configuration. How much more is running on the host in parallel (like is host memory overcommitted)?

I am marking the Precise task FixReleased (unknown fix), and closing WONTFIX the Oneiric one. We cannot replicate it anymore; even more, we never saw this issue outside KVM.

The workaround for Oneiric is, as noted in the comments above, to increase the VM's memory allocation.
