libvirt qemu cannot access image inside my home directory, even as root?












1















I have problem getting my VM running via libvirt. Here is my setup:




  • I put my qcow2 image and domain XML (named win7.xml) under $HOME/vm,
    with all files and directories using my user, my group, and permission bits 0644.


  • I uncommented user = "root", group = "root" and dynamic_ownership = 1
    lines in /etc/libvirt/qemu.conf, expecting qemu-system-x86_64 will run
    as root, therefore having full access to the dirs and files under $HOME/vm.



However, invocation of virsh create win7.xml as root was failed:



error: Failed to create domain from win7.xml

error: internal error: early end of file from monitor, possible problem: 2016-10-01T03:36:02.049418Z qemu-system-x86_64: -drive file=/home/naitree/vm/win7/win7.qcow2,format=qcow2,if=none,id=drive-virtio-disk0: Could not open '/home/naitree/vm/win7/win7.qcow2': Permission denied


The following error was logged in /var/log/libvirt/qemu/win7.log:



2016-10-01T03:36:02.049418Z qemu-system-x86_64: -drive file=/home/naitree/vm/win7/win7.qcow2,format=qcow2,if=none,id=drive-virtio-disk0: Could not open '/home/naitree/vm/win7/win7.qcow2': Permission denied

2016-10-01 03:36:02.080+0000: shutting down


It looks like qemu failed to access my VM disk file. But why? Didn't qemu-system-x86_64
run as root? What should be done to make sure libvirt-qemu able to access the disk image
residing in $HOME directory?



Additional version informations:




  • libvirt, virsh version: 1.3.3.2

  • QEMU version: QEMU emulator version 2.6.1 (qemu-2.6.1-1.fc24)

  • distro: Fedora 24

                    Is this a new Fibonacci Identity?

                    Image
                    6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
