Chroot issue with username to uid
I'm setting up a chroot environment on a shared web server to allow users to
modify their web roots within a secure chroot, but am having a problem.
Right now when I log in with test accounts I get this...

Sudo #includedir function ignored CentOS 6
I am unable to get the #includedir function to work with sudo. This works
just fine on all my CentOS 5.6 servers, but on 6 it is being ignored. I
have this line in the file /etc/sudoers.d/zabbix-puppet
zabbix ALL=NOPASSWD: /var/lib/zabbix/bin/start_puppet
However sudo still requires a password. If I put that same line into
/etc/sudoers file , there is no password prompt. At the end of my

Running Apache sites as separate users
I had a recent request to improve security on my web servers by having each
website use a different user to run the hosting service. So
example1.comhas it's own Apache instance running as apache1 and then
example2.com has its own instance of Apache as apache2. Is this even
possible or realistic? I understand the idea of how that would be secure,
much like creating a virtual machine to

Excluding RAW disk from snapshot
I have an oVirt engine node that currently runs the system on a qcow2
based virtual disk, and an NFS export volume on RAW. I'd like to take
a snapshot before a somewhat risky upgrade of oVirt and can't with the
raw image attached.
Looking at the documentation for the snapshot XML, I created this XML
file for the snapshot

CentOS 6 and KVM woes
I have decided to migrate my latest KVM server to CentOS 6.0 and am
beginning to get a little frustrated with some issues that worked perfectly
in 5.6.
Right now I've given up on getting virbr0 and NAT to work, but now I need
networking bridging to work, but nothing seems to fix the issue. I have not
had much experience with troubleshooting KVM so could really use some
pointers on resolving

Re: Live Migration Issue
Sorry, ctrl entered.
I'm hoping someone here can help me figure out what's going on here.
I've got two CentOS 7 hosts with shared storage that I'm trying to do live
migrations between and I'm running into an error with VMs that were
originally created on a CentOS 6 host and then moved the CentOS 7 hosts.
The CentOS 6 VM runs fine on the host, and can do non-live

how to add file-based disk space to a guest
hi there,
I'm following these documentations to add a file-based disk volume to
a KVM guest under Centos 6.0 :
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/chap-Virtualization-Storage_Volumes.html
as instructed, I created a "pool" then a "volume", file-based, e.g :
mkdir /mnt/raid/kvm_pool1

Hi,
I caught your mail in my Spam folder for some reason, maybe the same
happened for others. I don't have that deep knowledge of the snapshots,
but I'm replying so that if someone else has it in Spam and they have
more insight, they can reply.

Re: Live migration with non-shared ZFS volume
Hi Martin,
in the meantime, I've found a solution which I consider at least acceptable:
1. create zfs snapshot of domain disk (/dev/zstore/test-volume)
2. save original XML domain definition
3. create snapshot in libvirt like this:
virsh snapshot-create --xmlfile snap.xml --disk-only --no-metadata
test-domain
snap.xml:

Live migration with non-shared ZFS volume
Hi all,
I'm using ZFS on Linux block volumes as my VM storage and want to do live
migrations between hypervisors.
If I create ZFS snapshot of used volume on source host, send it do
destination host (zfs send/recv) and then run live migration with
VIR_MIGRATE_NON_SHARED_DISK
flag, the migration works OK.
But this procedure copies the whole disk twice which is a huge downside.

SELinux triggered during Libvirt snapshots
I recently began getting periodic emails from SEalert that SELinux is
preventing /usr/libexec/qemu-kvm "getattr" access from the directory I store
all my virtual machines for KVM.
All VMs are stored under /vmstore , which is it's own mount point, and
every file and folder under /vmstore currently has the correct context that

Using Samba to share Apache web root, securely
I'm setting up a shared web server running Apache. Each web root will
belong to a department, which has a corresponding Active Directory group to
give access. So far I've got samba working and such, but am having some
trouble wrapping my head around the necessary permissions to make all this
work, especially securely. So far I've found that both the POSIX and the
ACL permissions
