[libvirt] route seems to be not affecting the network behavior
by pichon
Hello,
I’m trying to set a default gateway on an isolated lan (because one of my VM get access to an other lan).
I’m trying to use the option <route > but this doesn’t affect the default route on my VMs.
Here is the network xml
<network>
<name>prd-private-lan</name>
<uuid>2222222222222222222222</uuid>
<bridge name='virbr3' stp='off' delay='0'/>
<mac address='52:54:00:08:1e:d8'/>
<domain name=‘pre' />
<dns>
<forwarder addr='8.8.4.4'/>
<forwarder addr='8.8.8.8'/>
</dns>
<ip address='10.10.0.1' netmask='255.255.255.0'>
<dhcp>
<range start='10.10.0.128' end='10.10.0.254’/>
<host mac=‘xxxxxx' name=‘finternet.pret' ip='10.10.0.7'/>
</dhcp>
</ip>
<route address='10.10.0.0' netmask='255.255.255.0' gateway='10.10.0.7'/>
</network>
And here is what I get on the guest VM connected to the pre-private-lan
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.0.0 0.0.0.0 255.255.255.0 U 100 0 0 ens4
Can someone help me or tell me what to do ?
What I’m a bit surprise is the file //var/lib/libvirt/dnsmasq/prd-private-lan.conf doesn’t contain any clause defining the new gateway. Something like ‘dhcp-option=3,10.10.0.7'
strict-order
no-resolv
server=8.8.4.4
server=8.8.8.8
domain=prd.pipiche.net
expand-hosts
pid-file=/var/run/libvirt/network/prd-private-lan.pid
except-interface=lo
bind-dynamic
interface=virbr3
dhcp-option=3
no-resolv
dhcp-range=10.10.0.128,10.10.0.254
dhcp-no-override
dhcp-lease-max=127
dhcp-hostsfile=/var/lib/libvirt/dnsmasq/prd-private-lan.hostsfile
addn-hosts=/var/lib/libvirt/dnsmasq/prd-private-lan.addnhosts
Of course I can add an explicit route on the guest - so did I - but for maintenance purposes I would like to avoid and have all configuration in the network XML
Thanks in advance

[libvirt] [PATCH 00/13] vbox: more error checking
by Ján Tomko
Check for return values of libvirt's internal APIs in vboxDumpVideo
and vboxDumpDisplay.
Patch 10/13 should fix a complaint by Coverity (untested).
Lots of whitespace changes, -b is your friend.
Ján Tomko (13):
Check return value of vboxDumpVideo
vboxDumpDisplay: reduce indentation level
vboxDumpDisplay: more indentation reducing
vboxDumpDisplay: add addDesktop bool
vboxDumpDisplay: remove extra virReportOOMError
vboxDumpDisplay: split out def->graphics allocation
vboxDumpDisplay: allocate the graphics structure upfront
vboxDumpDisplay: fill out the graphics structure earlier
vboxDumpDisplay: clean up VIR_STRDUP usage
vboxDumpDisplay: check return of virDomainGraphicsListenSetAddress
vboxDumpDisplay: use VIR_APPEND_ELEMENT
vboxDumpDisplay: reuse the keyUtf16 variable
vboxDumpDisplay: remove suspicious strlen

however forgot to update stump that's used on systems without
CGroups causing a build failure.

[libvirt] [PATCH 0/7] storage:dir: ploop volumes support
by Olga Krishtal
This series of patches is aimed to support ploop volumes directory storage
pools.
Ploop is a disk loopback block device, not unlike loop but with many features
like dynamic resize, snapshots, backups etc. Container images will be stored
in ploop volumes, that can be manipulated via virsh api.

[libvirt] Fwd: Virtualization in High-Performance Cloud Computing (VHPC '16)
by VHPC 16
====================================================================
CALL FOR PAPERS
11th Workshop on Virtualization in High-Performance Cloud Computing (VHPC
'16)
held in conjunction with the International Supercomputing Conference - High
Performance,
June 19-23, 2016, Frankfurt, Germany.
====================================================================
Date: June 23, 2016
Workshop URL: http://vhpc.org
Lightning talk abstract registration deadline: February 29, 2016
Paper/publishing track abstract registration deadline: March 21, 2016
Paper Submission Deadline: April 25, 2016
Call for Papers
Virtualization technologies constitute a key enabling factor for flexible
resource
management in modern data centers, and particularly in cloud environments.
Cloud providers need to manage complex infrastructures in a seamless
fashion to support
the highly dynamic and heterogeneous workloads and hosted applications
customers
deploy. Similarly, HPC environments have been increasingly adopting
techniques that
enable flexible management of vast computing and networking resources,
close to marginal
provisioning cost, which is unprecedented in the history of scientific and
commercial
computing.
Various virtualization technologies contribute to the overall picture in
different ways: machine
virtualization, with its capability to enable consolidation of multiple
underutilized servers with
heterogeneous software and operating systems (OSes), and its capability to
live-migrate a
fully operating virtual machine (VM) with a very short downtime, enables
novel and dynamic
ways to manage physical servers; OS-level virtualization (i.e.,
containerization), with its
capability to isolate multiple user-space environments and to allow for
their coexistence
within the same OS kernel, promises to provide many of the advantages of
machine
virtualization with high levels of responsiveness and performance; I/O
Virtualization allows
physical NICs/HBAs to take traffic from multiple VMs or containers; network
virtualization,
with its capability to create logical network overlays that are independent
of the underlying
physical topology and IP addressing, provides the fundamental ground on top
of which
evolved network services can be realized with an unprecedented level of
dynamicity and
flexibility; the increasingly adopted paradigm of Software-Defined
Networking (SDN)
promises to extend this flexibility to the control and data planes of
network paths.
Topics of Interest
The VHPC program committee solicits original, high-quality submissions
related to
virtualization across the entire software stack with a special focus on the
intersection of HPC
and the cloud. Topics include, but are not limited to:
- Virtualization in supercomputing environments, HPC clusters, cloud HPC
and grids
- OS-level virtualization including container runtimes (Docker, rkt et al.)
- Lightweight compute node operating systems/VMMs
- Optimizations of virtual machine monitor platforms, hypervisors
- QoS and SLA in hypervisors and network virtualization
- Cloud based network and system management for SDN and NFV
- Management, deployment and monitoring of virtualized environments
- Virtual per job / on-demand clusters and cloud bursting
- Performance measurement, modelling and monitoring of virtualized/cloud
workloads
- Programming models for virtualized environments
- Virtualization in data intensive computing and Big Data processing
- Cloud reliability, fault-tolerance, high-availability and security
- Heterogeneous virtualized environments, virtualized accelerators, GPUs
and co-processors
- Optimized communication libraries/protocols in the cloud and for HPC in
the cloud
- Topology management and optimization for distributed virtualized
applications
- Adaptation of emerging HPC technologies (high performance networks, RDMA,
etc..)
- I/O and storage virtualization, virtualization aware file systems
- Job scheduling/control/policy in virtualized environments
- Checkpointing and migration of VM-based large compute jobs
- Cloud frameworks and APIs
- Energy-efficient / power-aware virtualization
The Workshop on Virtualization in High-Performance Cloud Computing (VHPC)
aims to
bring together researchers and industrial practitioners facing the
challenges
posed by virtualization in order to foster discussion, collaboration,
mutual exchange
of knowledge and experience, enabling research to ultimately provide novel
solutions for virtualized computing systems of tomorrow.
The workshop will be one day in length, composed of 20 min paper
presentations, each
followed by 10 min discussion sections, plus lightning talks that are
limited to 5 minutes.
Presentations may be accompanied by interactive demonstrations.
