VirtFS accessmode
Hi all, I'm trying to share a folder between a host and a guest using VirtFS. The source is NAS mounted on the host and QEMU runs as unprivileged user. The only way for me to use the folder inside the guest is to set the access mode to 'squash' but all file operations are performed by the user running QEMU. If I ran QEMU as root, the passthrough mode works as expected. Is there

[PATCH -v2] btrfs: Use correct values when updating inode i_size on fallocate
Even though we allocate more, we should be updating inode i_size as per the arguments passed Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> --- Changes from V1: We should update i_size only if actual_len and cur_offset are both larger than i_size. Otherwise if actual_len is < i_size and cur_offset > i_size we may end up setting wrong i_size value

git running very slow
Hello Tim, Thank you for the information. I am wondering if anyone else is facing the same issue? Or it is just that my institute firewall is creating the problem.

How to change virtfs/9p/v9fs umask
Hi there. My question is regarding virtfs/9p/v9fs [1], not sure what's the appropiate name :) Basically I have a KVM + libvirt server sharing a directory with a guest in mapped mode. It works fine, but the only issue is with the file permissions of the files created by the guest inside the host: -They are 0700 for dirs and 0400 for files -The files belongs to the same user that runs the

[GSoC] Polly as an Analysis pass in LLVM
Hello All, I would like to propose "Polly as an Analysis pass in LLVM <https://docs.google.com/document/d/1QyUzL3OOwJSI91lDqr7VsvqUsFyTY9FlpAwbGSipUtw/edit>" as my project for this years GSoC. The broad idea is to provide an API to Polly's dependence framework and integrate it to Loop Vectorizer. Kindly share your thoughts and help me improve the proposal. Regards, Utpal

[PATCH] 9p/trans_virtio.c: Fix broken zero-copy on vmalloc() buffers
The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. However, that approach produces an invalid page address when we read/write to vmalloc buffers, such as those used for Linux kernle modules. This causes QEMU to die printing:

[GSoC 2016] Introduction - Polly as an Analysis pass in LLVM
Dear All, I am glad to be part of GSoC 2016 with LLVM organization. I am a first year PhD student at IIT Hyderabad, India and my research area is compiler optimizations using polyhedral model. My GSoC 2016 project is to implement Polly as an Analysis pass in LLVM [1]. We have a discussion on Polly-dev mailing list [2] on taking a better approach to implement this project. Based upon this

Broken OS when booting rootfs from 9p share
Hello, I've been trying to boot a VM with the rootfs being a 9P share from the host. The VM OS is centos 7. The OS boots but no services can work and it appears that the authentication system is broken. Now the funny thing is that booting the same OS on the same 9P share manually with Qemu works as expected with a fully functionnal OS... So I'm wondering what could libvirt do that render
