There are limitations in SRE-V regarding tracking real time hardware events such as the failure of a hard drive. The Service Ready Engine Virtualization platform (SRE-V) has VMware ESXI 5.0 built into the platform which provides virtualization, and SRE-V installs onto the Service Ready Engine (SRE) service module . ESXI utilizes a technology called CIM as well as SNMP with some limitations to track hardware events. SRE-V uses a software RAID developed by Promise and the release implemented d ...Read More

My VMs (CentOS6.2) residing on two different SRE are unable to talk to each
Answer
6/26/12 6:24 PM
I have two ISR G2 (Cisco3900) routers.
there network domain being 10.104.231.64-79 255.255.255.240
 
my default router is 10.104.231.65
My two ISR G2 have IP assigned as
---10.104.231.71 (ISR G2 )
-------- 10.104.231.74 (SRE module having EXSI 4.1) (its SM 3/0)
--------------10.104.231.75 (VM runing centos 6.2)
---10.104.231.72 (ISR G2 )
-------- 10.104.231.76 (SRE module having EXSI 4.1) (its SM 4/0)
--------------10.104.231.77 (VM runing centos 6.2)
 
(a) The problem is i am unable to ping 10.104.231.75 from outside network.
same thing goes with  10.104.231.77 (unable to ping from outside)
(b) i am able to ping both the ISRs (ip 71 and 72 from outside network)
(c) i am able to ping both the SRE (ip 74 and 76 from outside network)
(d) i am able to ping both the VMs (ip address 75 and 77) from both the ISRs respectively (ip 71 and 72)
(e) i am able to ping SRE (both) and ISR(both) from any of the VMs (ip 75 and 77)
(f) Traceroute (tracert 10.104.231.75) shows i am able to reach upto isr with ip 71 but after that packets get lost.
 
PS:
(1) i have attached the route table of both the ISRs.
(2) i have attached the tracert for vm with ip 75.
(3) i have attached the setup (VM hypervisor) snapshop.
 
Question:-
why i am unable to ping the VM as stated in (a). can somebdy plz point me to what i am missing??
Also is it because i am using the same vmk0 interface??

Hi Himanshu,

If you haven't resolved this issue, it looks to me like your configuration is correct for SM 3/0, but I don't see any ip routes or the configuration for your SM4/0 interface. You'll need to add IP routes for the SM4/0 interface as well.

Thanks,

Brett

Hi Himanshu,

you have to create one more vm network from vswitch0 and add your vm to that network and vm route to sm 4/0.
