I got a system that is hung, unable to do most unix commands like ps/who etc... I did: dtrace -c /usr/bin/ps -n ''pid$target::open*:entry {printf("%s %s",execname,copyinstr(arg0)); }'' and it hangs here: 7 65277 open:entry ps /proc/19729/psinfo 7 65277 open:entry ps /proc/11687/psinfo ^C So, I tried to kill -9 11687, but that returns with nothing. If I do "ls /proc", I still see it. I am unable to cd into /proc/11687/psinfo either. Anything else I can do other than reboot? -- This message posted from...

Hello, This is another iteration of the virtio-pstore work. I've addressed all comments from Daniel Berrange on the qemu side. * changes in v4) - use qio_channel_file_new_path() (Daniel) - rename to delete_old_pstore_file (Daniel) - convert G_REMOVE_SOURCE to FALSE (Daniel) * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests

Hello, This is v2 of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version. Limiting disk size is not implemented yet. * changes in v2) - update VIRTIO_ID_PSTORE to 22 (Cornelia, Stefan) - make buffer size configurable (Cornelia) - support PSTORE_TYPE_CONSOLE (Kees) - use separate virtqueues for read and write - support concurrent async

Hello, This patchset is a proof of concept of virtio-pstore idea [1]. It has some rough edges and I'm not familiar with this area, so please give me feedbacks and advices if I'm going to a wrong direction. It started from the fact that dumping ftrace buffer at kernel oops/panic takes too much time. Although there's a way to reduce the size of the original data, sometimes I want to

Hello, This is another iteration of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version and drooped the support for PSTORE_TYPE_CONSOLE for simplicity. It'll be added once the basic implementation * changes in v3) - use QIOChannel API (Stefan, Daniel) - add bound check for malcious guests (Daniel) - drop support PSTORE_TYPE_CONSOLE for now
