HPivm guest intermitent packet loss
Hi,
We ha a HPIVM 4.2.5 host in a rx7640:

The host has 4 VMs, 3 VMs have no network problems and work fine, a fourth VM has almost constant bad ping times over 800ms on the local(and also the default gw) network, and some times it looses all network conectivity during short spells. This happens in all the NICs it has attached that are part of Vswitches in different Lans.
Cheking the VMs resources, cpu/mem/disk, they are almos IDLE all the time on the guest VM, so it doesn't seem it's running out of resources
The network stats for the VM guest on the vswiches from the host, show no problems.
Info from the guest:
# swlist -l bundle | grep OE

it's giving on the guest:
Dead gateway detection can't ping the last remaining default gateway at 0xa714001 .See ndd -h ip_ire_gw_probe for more info Dead gateway detection can't ping the last remaining default gateway at 0xa714001 .See ndd -h ip_ire_gw_probe for more info
I have disabled the gw probing, but problems still continue, i have a ping running and you can check the high rtt times, on all nics on the guest:
03/08/14 21:11 ping 14688 ms local ping-gw.txt
03/08/14 21:11 ping 13678 ms ping-local.txt
03/08/14 21:11 ping 12658 ms ping-ext.txt
This doesn't happen in the other VMs, the other machines have the same OE,AVIO and patches,etc.
Any idea where I can keep looking?.
Thanks

Re: HPivm guest intermitent packet loss
After watching packet loss in other interfaces of the virtual machine, I took a longer look at the VM OS resources, and this time I spotted very short burst of cpu and disk activiy, that leave the VM during and interval of one or 2 seconds unresponsive.
Here is the sar -d output with service times over the roof:
10:35:53 disk6 100.00 3.00 1 2 5794.79 22189.95
10:35:55 disk6 100.00 1.50 1 2 11593.92 2645.25
10:35:56 disk5 100.00 7.40 1 12 3624.67 12190.01
disk6 91.16 0.40 2 98 23967.29 4553.04
And the cpu is all in sys:
10:35:53 0 100 0 0
10:35:55 0 100 0 0
This coincides in time with the high pings:
06/08/14 10:35 ping 18090 ms ping-local.txt
06/08/14 10:35 ping 14281 ms ping-gw.txt
If I do a read/write test to the disks using dd, there is no problem, the service times are good, so there has to be a short lived process or somthing that is hogging the system, but because it only lasts seconds I can't get hold of it.
Any ideas?.
thnx
