My test is very simple - i have 3.18.3 vanilla kernel with compiled in virtio drivers and custom initrd that contains only one binary - binary written in golang. I have prebuilded images (builded from packer - raw qemu image) that compressed by bgzf (parallel gzip encoder/decoder). After vm starts it fetches image from http server on the fly decompress and write to disc. After write successed it send sync to fs and restart vm. So i have this works fine with qemu and plain lvm, on unpatched qemu 2.3.0 with limiting bandwidth or installing only on vm at the same time all works fine, but if vm count more than 3-5 at the same time for one node i have errors that i send to list. If this version of patch does not helps i'm tr to rewrite vm installer and share it in boxed variant and send instructions how to run it in qemu. -- Vasiliy Tolstov, e-mail: v.tols...@selfip.ru -- sheepdog mailing list sheepdog@lists.wpkg.org https://lists.wpkg.org/mailman/listinfo/sheepdog
