RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Release Note
Doc Text:
Pulling System Entropy from Host A new device, virtio-rng, can be configured for guests, which will make entropy available to guests from the host. By default, this information is sourced from the host's /dev/random file, but hardware random number generators (RNG) available on hosts can be used as the source as well.

Comment 2 Amos Kong 2013-07-30 06:40:14 UTC 
We already have virtio-rng support in latest qemu-kvm-rhel7.
I assume that what I need to do more is confirming it works in rhel7.

1) use assigned backend
# qemu-kvm-rhel7 -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 -vnc :0 -snapshot /images/RHEL-Server-7.0-64-virtio.qcow2 --enable-kvm

2) use default backend
# qemu-kvm-rhel7 -device virtio-rng-pci -vnc :0 -snapshot /images/RHEL-Server-7.0-64-virtio.qcow2 --enable-kvm
