Re: vhost-net requested but could not be initialized
Currently in the VM XML, I am passing the following command line argument as a passthrough argument: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on -device virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off Is there another way to represent this in the XML file? maybe that may solve the problem.

Passing llvm option -mem2reg to clang
I have my own llvm pass which requires mem2reg. It worked fine with opt. However, I was trying to make it work with clang as I needed it to run some spec cpu benchmarks. Is there any way that I can mention mem2reg (PromotePass) pass as a pre-requisite in my own pass's implementation?

[PATCH 0/2] builder: Choose better weights in the planner.
It started out as "this'll be just a simple fix ..." and turned into something a bit over-engineered in the end. Here it is anyway. Rich.

vhost-net requested but could not be initialized
I am using a custom qemu to launch a vhost enabled VM. The qemu doesn't use the default "/dev/vhost-net" directory as character device. Due to this I am getting the error: qemu-system-x86_64: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net requested but could not be initialized ​Is there a way to tell libvirt to ​avoid using the default

[PATCH v2 0/2] builder: Choose better weights in the planner.
v1 -> v2: - Removed the f_type field from StatVFS.statvfs structure. - New function StatVFS.filesystem_is_remote, written in C. [Thinking about it, this should probably be called ?is_network_filesystem?, but I can change that before pushing]. - Use statvfs instead of fstatvfs, and statfs instead of fstatfs. - Rejigged the comments in builder/builder.ml to make them simpler

8000 security risk?
Yes I meant HTTPS over HTTP, which yes, I’m differentiating by those port numbers. Thanks for clarifying! We have been streaming HTTP for a long time, but I am at a university and there is a lot of emphasis on security. I was never really sure what the certificate did for us in this case…but was attempting to comply! Over the years we have had a small handful of IPs trying to maliciously access

Passing llvm option -mem2reg to clang
Hi, I was trying to pass llvm option -mem2reg to clang using -mllvm and I found the following error: clang (LLVM option parsing): Unknown command line argument '-mem2reg'. Try: 'clang (LLVM option parsing) -help' clang (LLVM option parsing): Did you mean '-debug'? I would appreciate if anyone could help me. -- Syed Rafiul Hussain

8000 security risk?
Hi all, Are there any serious security risks for leaving port 8000 open to public use on icecast? I had wanted to limit to 8443 but it seems some radio devices cannot support this protocol.

Re: vhost-net requested but could not be initialized
​The qemu that I am using isn't modified at all. It's the VHOST drivers that are mounted elsewhere i.e., not on default /dev/vhost-net. Here is the command that I use to launch my qemu VM: qemu-system-x86_64 -cpu host -boot order=c -hda /root/Disks/ubuntu1.qcow2 -m 1024M -smp 2 --enable-kvm -name 'client 1' -nographic -vnc :2 -net none -no-reboot -mem-path /dev/hugepages

Re: vhost-net requested but could not be initialized
Thanks Wangkai but libvirt infact pre-configures network tap devices and pre-opens /dev/vhost-net file and passes these to qemu as open, ready to use file descriptors. My issue is that my qemu requires that /dev/vhost-net directory is removed and it's kernel module be unloaded. Then it creates a vhost -net device using its own configuration.
