[Users] questions about vdsm supervdsmserver
hi,all. i have 2 questions about supervdsmserver, 1.why it is created separately as a daemon? its many function have never been used, and its function can be done by calling libvirt directly, why supervdsmserver is need? 2.it seems that only one supervdsmserver should be exist, by killing old ones to assure that . but look at this, and please explain to me. unix 2 [ ACC ] STREAM LISTENING 1339963 4968/python /var/run/vdsm/svdsm.sock unix 2 [ ACC ] STREAM LISTENING 384165 39716/python /var/run/vdsm/svdsm.sock unix 2 [ ACC ] STREAM LISTENING 1100509 49487/python /var/run/vdsm/svdsm.sock unix 2 [ ACC ] STREAM LISTENING 1326232 3813/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 1448193 4968/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 1447937 4968/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 1424959 4968/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 1414835 4968/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 1327873 3813/python /var/run/mcvda/svdsm.sock unix 2 [ ] STREAM CONNECTED 1309612 49487/python /var/run/mcvda/svdsm.sock unix 3 [ ] STREAM CONNECTED 384221 39716/python /var/run/mcvda/svdsm.sock thanks___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Ah, ok. SO after reading http://wiki.libvirt.org/page/Qemu_guest_agent some questions can we use ootb qemu-guest-agent with ovirt 3.2.1 if we have for example a CentOS 6 guest (with qemu-guest-agent-0.12.1.2-2.355)? Does oVirt create a virtio-serial port to communicate with libvit and does it use libvirt with any options to quiesce fs on guest? iirc, it should work - testing/feedback would be welcome. I believe vdsm does not create the virtio-serial port when starting the VM, so you'd have to modify this behaviour with hooks [1]. Once you do that, whenever you create a live snapshot vdsm will notify libvirt to quiesce first. Note that afaik, quiesce in qemu-ga is only supported for Linux guests. Really cool to hear how things are progressing! The qemu-ga quiesces what exactly? The guest filesystem? What about potential applications that might be running inside the guest? Can you call live snapshots of a linux guest Application Consistent? The good thing about Microsoft VSS is that MS applications are registered to VSS so that when you trigger VSS to quiece, all of the other applications are told to pause as well. /Karli VSS quiesce support patches have been submitted, but I'm not sure what the status is there yet. [1] Hooks preso: http://www.ovirt.org/File:OVirt-hooks-netapp-jan2013.odp Can one use as an alternative the command fsfreeze in CentOS 6.4 guest (even if in tech preview) as in : https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Technical_Notes/storage.html what i remember is that it supposed to be pluggable/configurable for you to run the relevant commands you want. ayal may remember better ___ Users mailing list Users@ovirt.orgmailto:Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- Med Vänliga Hälsningar --- Karli Sjöberg Swedish University of Agricultural Sciences Box 7079 (Visiting Address Kronåsvägen 8) S-750 07 Uppsala, Sweden Phone: +46-(0)18-67 15 66 karli.sjob...@slu.semailto:karli.sjob...@adm.slu.se ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

you'll probably get more answers on vdsm-devel (cc'd). bcc'd users to avoid dupes.
