[libvirt] [PATCH V1 0/4] Support for multiple IP addresses using lists
by Stefan Berger 23 Oct '11

23 Oct '11

This patch series builds on the previously posted patch series https://www.redhat.com/archives/libvir-list/2011-October/msg00912.html and introduces the capability to assign a list to a variable and have multiple rules instantiated, one for each item in the list. This means, that if for example a variable like IP has been assigned the following values IP = [1.2.3.4, 5.6.7.8, 10.0.0.1] it will generate 3 rules, which then in turn allows us to build filters that can evaluate multiple possible values per field, i.e., allow the filtering for multiple IP addresses (per interface). It would then need David Steven's patch for support of 'RETURN' (and 'CONTINUE') target(s). Regards, Stefan

[libvirt] passing secrets to block devices
by Josh Durgin 21 Oct '11

21 Oct '11

We're working on libvirt support for block device authentication [1]. To authenticate, rbd needs a username and a secret. Normally, to avoid putting the secret on the command line, you can store the secret in a file and pass the file to qemu, but when this is automated, there's no good way to know when the file can be removed. There are a few ways to pass the secret to qemu that avoid this problem: 1) pass an fd to an unlinked file containing the secret This is the simplest method, but it sounds like qemu developers don't like fd passing from libvirt. [2] 2) start guests paused, without disks requiring authentication, then use the drive_add monitor command to attach them This would make disks with authentication somewhat of a special case in libvirt, but would be simple to implement, and require no qemu changes. 3) start guests paused, then send the secret via a new QMP/HMP command (block_set_conf <key> <value>?) This is a larger change, but it would be more generally useful for changing configuration at runtime. What do you think is the best approach?
