Hi all,
I have a Solaris VM in my vSphere environment with this specifications:
- Virtual Machine Version: 4
- Memory: 6144MB
- CPUs: 2
- HardDisk1: 30GB
- HardDisk2: 180GB
- SCSI controller: LSI Logic Parallel
- vSphere 5
- Kernel: 142910-17
- Release: Solaris 10 x64 u9
The VM was running fine until I added more memory. I turned off the VM, I edited the settings and I extended the memory to 12G. When the machine boots for the first time I noticed that it takes longer than previous boots. And when I try to start an Oracle database or doing some filesystem task, like coping big files it goes too slow. The CPU usage goes to the 100% and if I do a "sar" I can see that the "sys" eats about an 90% of the CPU. When I'm doing this tasks the VM hardly freezes and if I do something else, like a "su -" takes about 15 minutes.
I have undone the changes, the VM returns to have 6G of RAM, and the boot is faster and the systems has improved his behavior.
Must I have to do something else to extend the memory in a Solaris 10 VM?
Thanks in advance
