Hi Alexandre
Many thanks for your reply, and here my answer and comments:
is multicast working ?
Yes
Here a better explanation:
- I have 8 nodes in a PVE cluster.
- 5 Nodes have PVE 3.3 version with the Kernel 3.10.0-19 version
- 3 Nodes have PVE 2.3 version with the Kernel 2.6.32-19 version
Hi Cesar,
first question :
is multicast working ?

Hi, here the new version with hugepages.
http://odisoweb1.odiso.net/qemu-server_3.3-6_amd64.deb
vmid.conf
-
hugepages: 2 for 2M hugepages
hugepages: 1024 for 1G hugepages
for 1G hugepage, you need to add hugepagesz=1G in your grub options, and this
work only with recent processor (intel
config
--
hugepages: 2|1024
2: enable 2M hugepages
1024 : enable 1G hugepages
1G hugepages need to be enable at boot with grub option : hugepagesz=1G,
and it's working only on new processor (>westmere for intel processor and also
recent amd)
This is working with or without numa

This add support for manually defined hugepages,
which can be faster than transparent hugepages for some workload like databases

Hi Alexandre
Until you correct the problem, and for avoid the loss of cluster
communication in these two nodes, can be a temporal solution that I add to
rc.local file this line:
/usr/bin/pvecm expected 1
As i don't have a fence device by Hardware, and i know that for apply HA
with manual fen
Thank you very much for the offer, but until now i don't understand as how
my VM can gain speed, and as i understand:
a) My VM (Win 2008R2) can not use hugetlbfs
b) Hugepages of 1 GB. is recommended for nodes with some terabytes of RAM,
and my VM only has assigned 251 GB. of RAM.
Can you expla
