[libvirt] ACLs for libvirt
by Michal Privoznik 25 Nov '11

25 Nov '11

Hi all, I'd like to implement this new feature for libvirt. However, I think we should settle down on design first. My biggest concern is choosing the right level on on which ACLs will be implemented. Should be interested only in (user, API), or with more granularity (user, API, API's parameters)? Or should we take the RBAC path? How should we even identify and authorize users? My initial though is to create framework which can be used then to implement ACLs on any level we want. What's our opinion? Michal

[libvirt] [PATCH] conf: Don't drop console definition on domain restart
by Michal Privoznik 25 Nov '11

25 Nov '11

One of my latest patches 2e37bf42d28d8bb5d045b206587c64643c64d02a copy serial console definition. On domain shutdown we save this info into state XML. However, later on the daemon start we simply drop this info and since we are not re-reading qemu log, vm->def->consoles[0] does not get populated with copy. Therefore we need to avoid dropping console definition if it is just alias for serial console. --- src/conf/domain_conf.c | 76 +++++++++++++++++++++++++++++++++++++++++++---- 1 files changed, 69 insertions(+), 7 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index d365cee..f04e477 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -1042,6 +1042,57 @@ void virDomainChrSourceDefFree(virDomainChrSourceDefPtr def) VIR_FREE(def); } +/* virDomainChrSourceDefIsEqual: + * @src: Source + * @tgt: Target + * + * Compares source and target if they contain + * the same information. + */ +static bool +virDomainChrSourceDefIsEqual(const virDomainChrSourceDef *src, + const virDomainChrSourceDef *tgt) +{ + if (tgt->type != src->type) + return false; + + switch (src->type) { + case VIR_DOMAIN_CHR_TYPE_PTY: + case VIR_DOMAIN_CHR_TYPE_DEV: + case VIR_DOMAIN_CHR_TYPE_FILE: + case VIR_DOMAIN_CHR_TYPE_PIPE: + return STREQ_NULLABLE(src->data.file.path, tgt->data.file.path); + break; + case VIR_DOMAIN_CHR_TYPE_UDP: + return STREQ_NULLABLE(src->data.udp.bindHost, tgt->data.udp.bindHost) && + STREQ_NULLABLE(src->data.udp.bindService, tgt->data.udp.bindService) && + STREQ_NULLABLE(src->data.udp.connectHost, tgt->data.udp.connectHost) && + STREQ_NULLABLE(src->data.udp.connectService, tgt->data.udp.connectService); + break; + case VIR_DOMAIN_CHR_TYPE_TCP: + return src->data.tcp.listen == tgt->data.tcp.listen && + src->data.tcp.protocol == tgt->data.tcp.protocol && + STREQ_NULLABLE(src->data.tcp.host, tgt->data.tcp.host) && + STREQ_NULLABLE(src->data.tcp.service, tgt->data.tcp.service); + break; + case VIR_DOMAIN_CHR_TYPE_UNIX: + return src->data.nix.listen == tgt->data.nix.listen && + STREQ_NULLABLE(src->data.nix.path, tgt->data.nix.path); + break; + + case VIR_DOMAIN_CHR_TYPE_VC: + case VIR_DOMAIN_CHR_TYPE_STDIO: + case VIR_DOMAIN_CHR_TYPE_SPICEVMC: + /* nada */ + return true; + } + + /* This should happen only on new, + * yet unhandled type */ + + return false; +} + void virDomainChrDefFree(virDomainChrDefPtr def) { if (!def) @@ -7308,6 +7359,7 @@ static virDomainDefPtr virDomainDefParseXML(virCapsPtr caps, goto no_memory; for (i = 0 ; i < n ; i++) { + bool create_stub = true; virDomainChrDefPtr chr = virDomainChrDefParseXML(caps, def, nodes[i], @@ -7325,7 +7377,9 @@ static virDomainDefPtr virDomainDefParseXML(virCapsPtr caps, * So if we see that this console device should * be a serial device, then we move the config * over to def->serials[0] (or discard it if - * that already exists + * that already exists).

[libvirt] 'savevm/loadvm' monitor command sequence losing mouse state across a VM restore
by Vincent Passaro 24 Nov '11

24 Nov '11

All eblake on #virt requested that I ask the question here before posting on bugzilla, so I wanted to check if anyone has seen this issue. I create a vm snapshot (with F16) using virsh snapshot-create I then restore the vm with virsh snapshot-restore After the restore succeeds I loose the ability to interact with the vm via mouse. Keyboard remains functioning, I can send commands to it via the Spice Console (CTRL-DEL), etc. I have tired killing X and restarting the machine with no success. To restore keyboard functionality I have had to restart libvirtd. Thoughts? R/ Vince

[libvirt] [PATCH v4 00/13] Implement keepalive protocol for libvirt RPC
by Jiri Denemark 24 Nov '11

24 Nov '11

This patchset can also be found at https://gitorious.org/~jirka/libvirt/jirka-staging/commits/keepalive This allows us to detect broken connections between server and client without waiting for TCP timeout and dead deamon/client. By default a connection is considered broken after about 30 seconds of no messages received from remote party. After that period, the connection is automatically closed. The main reason for implementing this is that peer-to-peer migration can now be canceled when a connection between source and target breaks. Although this will really work only after qemu fixes migrate_cancel command so that it doesn't block when outgoing TCP buffers are full. Version 4 addresses comments from Daniel and Matthias. Although most of the patches were already (conditionally) acked, I'm sending all of them to provide a complete picture of the change. Patches that were already acked are explicitly marked so in the Notes section so anyone can just skip them if they like.

[libvirt] [PATCH v3 0/2] API to invoke S3/S4 on a host and also resume from within libvirt
by Srivatsa S. Bhat 24 Nov '11

24 Nov '11

(This patch is positioned to go in after the patch that exports the host power management capabilities as XML, posted in [4]) This patch adds a new API to put a host to a suspended state (either Suspend-to-RAM or Suspend-to-Disk) and setup a timed resume to get the host back online, from within libvirt. This uses the RTC wakeup mechanism to set up a timer alarm before suspending the host, so that in-band resume is facilitated by the firing of the RTC alarm, which wakes up the host. The decision to use the RTC Wakeup mechanism to resume the host from sleep was taken in [1]. An initial API was discussed in [2]. Some design ideas for the asynchronous mechanism implementation was discussed in [3]. v3: * Rebased to libvirt 0.9.7 * Added a check to see if alarmTime (suspend duration) is within an acceptable range. v2: * Added an init function which finds out if S3/S4 is supported by the host, upon the first request to suspend/hibernate. * Added synchronization/locking to ensure that only one suspend operation is active at a time. v1: http://www.redhat.com/archives/libvir-list/2011-September/msg00830.html v2: http://comments.gmane.org/gmane.comp.emulators.libvirt/46729 References: [1]. http://www.redhat.com/archives/libvir-list/2011-August/msg00327.html [2]. http://www.redhat.com/archives/libvir-list/2011-August/msg00248.html [3]. http://www.redhat.com/archives/libvir-list/2011-September/msg00438.html [4]. http://www.redhat.com/archives/libvir-list/2011-November/msg00378.html Srivatsa S.

[libvirt] Release schedule for libvirt 0.9.8
by Daniel Veillard 24 Nov '11

24 Nov '11

To try to keep the monthly release schedule, I would suggest the following: - enter freeze in a week from now i.e. Dec 1st - try to push the release on Dec 6 or 7 Which means that we have one week to push the new APIs under review (S3/S4 support, various block io changes, ...), maybe with a bit of luck we can get the PPC KVM support in too. So let's focuse on reviewing, finalizing and pushing the existing patch sets :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
