ASF subversion and git services commented on CLOUDSTACK-9395: ------------------------------------------------------------- Commit c9e14c9f0885e8d8360f74997773aad16e9c8b19 in cloudstack's branch refs/heads/master from [~rajanik] [ https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=c9e14c9 ] Merge pull request #1572 from wido/virtio-rng CLOUDSTACK-9395: Add Virtio RNG device to Instances when configuredBy adding a Random Number Generator device to Instances we can prevent entropy starvation inside guest. The default source is /dev/random on the host, but this can be configured to another source when present, for example a hardware RNG. When enabled it will add the following to the Instance's XML definition: <rng model='virtio'> <backend model='random'>/dev/random</backend> </rng> If the Instance has the proper support, which most modern distributions have, it will have a /dev/hwrng device which it can use for gathering entropy. * pr/1572: CLOUDSTACK-9395: Add Virtio RNG device to Instances when configured Signed-off-by: Rajani Karuturi <rajani.karut...@accelerite.com> > Add VirtIO Random Number Geneator to KVM Instances > -------------------------------------------------- > > Key: CLOUDSTACK-9395 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9395 > Project: CloudStack > Issue Type: New Feature > Security Level: Public(Anyone can view this level - this is the > default.) > Components: KVM > Reporter: Wido den Hollander > Assignee: Wido den Hollander > Labels: kvm, libvirt, virtio > Fix For: Future > > > Add a VirtIO Random Number Generator (RNG) to all Instances to prevent > entropy starvation in guests. > More information: > - https://libvirt.org/formatdomain.html > - https://fedoraproject.org/wiki/Features/Virtio_RNG > In the end this make sure the Entropy performance in Instances is better -- This message was sent by Atlassian JIRA (v6.3.4#6332)
