Hi, I am trying to pass a Lustre directory mounted on the host to the guest. I can pass a local directory in just fine when starting an instance via virsh. I can execute the qemu command from libvirt's logs (dropping ?S flag) directly, and passing the Lustre mounted directory also works (but the network complains about different MAC address). However, when I start an instance using

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

Hi, I need to deploy a bunch of VMs, that need data from NFS shares residing on a network I don''t trust my VMs to connect to directly. What would it take for me to mount the shares on the hosts, and export them to my VMs using v9fs, for instance? In practice, only one of my VMs will access a portion of the NFS at a time, and the host won''t touch it at all, so I''m

I figured out the problem. There is zerocopy IO is being done via DMA to a buffer allocated with valloc(). Right now, I am running a hack-fix locally so I can get some other stuff done first. I will propose a proper fix to the list in a few days. On 11/25/2013 10:49 AM, Richard Yao wrote: > I booted a Gentoo Linux installation in QEMU with a 9P rootfs as follows: > > sudo qemu-kvm -cpu

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

Hi all, Here is the situation: I have 2 nodes MDS1 , MDS2 (10.0.0.22 , 10.0.0.23) I wish to use as failover MGS, active/active MDT with zfs. I have a jbod shelf with 12 disks, seen by both nodes as das (the shelf has 2 sas ports, connected to a sas hba on each node), and I am using lustre 2.4 on centos 6.4 x64 I have created 3 zfs pools: 1. mgs: # zpool

I have strange kernel panic Kernel 3.13.3 vanilla root is mounted via 9p virtfs (readonly). virsh --version 1.2.1 qemu --version QEMU emulator version 1.7.0, Copyright (c) 2003-2008 Fabrice Bellard systemd version 210 Domain config: <domain type='kvm'> <name>build</name> <uuid>328891df-b3c3-aee9-eb5d-00007e7934f7</uuid> <memory
