Oracle VM 3.4.x & PVM vs HVM PV
Initially when we started to use Oracle VM we did lot of performance testing and at that point we went with Paravirtualized VM’s (PVM) due to better performance we saw with them. Now with our recent upgrade to Oracle VM 3.4.2 if you are using hugepages (we do!) then hugepages are not supported anymore with…
Optimizing performance for Oracle VM when using iSCSI storage
We implemented Oracle VM 3.3.2 around two years ago and biggest issue we had was using iSCSI storage having sub-optimal latency and throughput with parallel sessions and high load in our performance tests. In the end this was resolved by linux disk partition alignment and few iSCSI optimizations. Problem After doing the initial Oracle VM installation we started…
Oracle OVS, Broadcom Netextreme II and 10G network
We recently upgraded our LAN network from 1G to 10G but the Oracle OVS servers network cards showed only 1G link even though the advertised link was 10G. [root@ovs1 ~]# ethtool em1 Settings for em1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Advertised link…
Upgrading Oracle VM 3.3.3 to 3.4.2
Now when we have used demo 3.4.2 for some time without issues I decided to upgrade our sandbox Oracle VM setup from 3.3.3 to 3.4.2 to get experience for the actual production upgrade coming later. We have two installations of Oracle VM. One is sandbox which has some old blade servers acting as OVS and…
Impressions on Oracle Enterprise Manager 13.2 & Oracle VM Infrastructure Home
I’ve played around with OEM 13.2 Oracle VM Infrastructure Home few days and I think it definitely has potential to be standard tool for us instead of OVM Manager! There are still some areas which could be improved and leave me wondering if they are good. Things I like: New GUI is nice and responsive…
Start using Oracle VM 3.4.2 through Oracle Enteprise Manager 13.2
One of my main interests after setting up Oracle VM 3.4.2 and Oracle Enterprise Manager 13.2 was to test how OEM 13.2 looks when you use Oracle VM through it. With OEM 12c we tested it but it seemed always lacking lot of functionality so day-to-day administration usage was lot easier with OVM Manager. Preliminary tasks…
Installing Oracle VM 3.4.2 (Part 1)
Moi! We currently use Oracle VM 3.3.3 quite heavily and look to improve our setup. So for that I decided to install latest Oracle VM 3.4.2. to see what improvements it brings. Oracle Virtualization blog has good summary on 3.4.2: https://blogs.oracle.com/virtualization/entry/oracle_vm_3_4_2 To install I had to download two files. One for OVM Manager and one…
Setup Oracle Enterprise Manager 13.2 from OVM template
Moikka! So this will be my first post. We currently use quite basic setup of OEM 12c but really want to see what 13.2 is capable as it has added some features to Exadata monitoring (or so I was told). Also what is really interesting is the improved manageability for OVM 3.4 directly through Enterprise Manager.…
