Thank you Daniel. How difficult to extend libvirt for this? One critical application on my VM needs to turn vnet_hdr off. I can switch to use qemu directly. However, in that way I will lose all the nice things provided by libvirt. Thanks, ~Jianfeng On 3/3/14 3:53 AM, "Daniel P.

Thank you Eric. Yes, it looks like AppArmor caused the problem. I will google on how to disable it.

Unfortunately my backing store file is not in a volume. So I guess I cannot use that method.

Hi, I am using libvirt and virsh to create my VM on KVM. It works fine. However, I need to turn off vnet_hdr for virtio interface. Does anyone know how to do it through libvirt? Thanks.

> Hi, libvirt experts, I used libvirt to create a VM and used backing store to a local file. It works fine until I installed my box to Unbuntu Trusty (14.04). I got the following errors when I tried to start the VM: Could not open backing file: Could not open <path to my backing file>: Permission denied However, if I moved my image file (not base image) to default location

Hi, How are you! I built a PXE server of MSDOS in Linux server, client can boot from network and login MSDOS, but by default, the output console is VGA, My target client has not VGA port, it can only output from serial port, so could you help to tell me how to boot a MSDOS client from network and keep the PXE client output console is serial port ? Below is the PXE configure file?s

Dear Mao Jianfeng, "r-help-owner" is not the place for help, but: r-help at r-project.org (CC-ed here) In any case, strsplit() does the job, i.e.: > unlist(strsplit("BCPy01-01", "-")) [1] "BCPy01" "01" You can work with the whole variable, like: splitpop <- strsplit(df1$popcode, "-") then access the first part with >

The failure reproduces with just 2 RDMA servers (with InfiniBand), one of those acts also as a client. I looked into logs. I paste lengthy logs below with

Dear all, This is a simple probability problem. I want to know, How to generate a normal distribution with mean=1, min=0.2 and max=0.8? I know how the generate a normal distribution of mean = 1 and sd = 1 and with 500 data point. rnorm(n=500, m=1, sd=1) But, I am confusing with how to generate a normal distribution with expected min and max. I expect to hear your directions. Thanks in

There's no support for disabling it - if we detect a host which supports it, it will be unconditionally enabled. Regards,
