LinuxSecurity.com: It was discovered that libvirt, a library for interfacing with different virtualization systems, did not properly check for read-only connections. This allowed a local attacker to perform a denial of service (crash) or possibly escalate privileges. [More...]
Hi all,
I would like to get some ideas and opinions on matter of libvirt netfilter application in KVM environment. I am looking for some easy way to control it with an API and possible experience with that and its performance in real life application.
Thanks for all ideas (0 Replies)
SYSTEMD-DETECT-VIRT(1) systemd-detect-virt SYSTEMD-DETECT-VIRT(1)NAME
systemd-detect-virt - Detect execution in a virtualized environment
SYNOPSIS
systemd-detect-virt [OPTIONS...]
DESCRIPTION
systemd-detect-virt detects execution in a virtualized environment. It identifies the virtualization technology and can distinguish full VM
virtualization from container virtualization.
When executed without --quiet will print a short identifier for the detected virtualization technology. The following technologies are
currently identified: qemu, kvm, vmware, microsoft, oracle, xen, bochs, chroot, uml, openvz, lxc, lxc-libvirt, systemd-nspawn.
If multiple virtualization solutions are used, only the "innermost" is detected and identified. That means if both VM virtualization and
container virtualization are used in conjunction, only the latter will be identified (unless --vm is passed).
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a short version string and exits.
-c, --container
Only detects container virtualization (i.e. shared kernel virtualization).
-v, --vm
Only detects VM virtualization (i.e. full hardware virtualization).
-q, --quiet
Suppress output of the virtualization technology identifier.
EXIT STATUS
If a virtualization technology is detected, 0 is returned, a non-zero code otherwise.
