XenServer Shared Local Stage

I have seen this issue many times. I really love xenserver, however, its like an unpolished gem...

you should check with ifconfig -a (on dom0, xenserver console ) and look for dropped packets

you can use: ifconfig -a | grep dropped | awk {'print $3'} | grep -v ":0"

if you see dropped packets , you should do:

1. On the Virtual Machines, Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. In the right pane, make sure that the DisableTaskOffload registry entry exists. If this entry does not exist, follow these steps to add the entry: a. On the Edit menu, point to New, and then click DWORD Value. b. Type DisableTaskOffload, and then press ENTER.
4. Click DisableTaskOffload.
5. On the Edit menu, click Modify.
6. Type 1 in the Value data box, and then press ENTER.
7. Exit Registry Editor.
8. Restart all Virtual Machines

and on server xenserver console:

Get the UUID of the physical interface: xe pif-list host-name-label=XEN1

Disable checksum on the interfaces:

xe pif-param-set other-config:ethtool-tx="off" uuid=3281b044-2a93-2f1b-e8e1-eaf0faccbd1f; xe pif-param-set other-config:ethtool-rx="off" uuid=3281b044-2a93-2f1b-e8e1-eaf0faccbd1f

I think that the fastest way to do the migration is to use a disk imaging software. In the company i work almost all the machines are hosted in XEN and VMWARE servers. We are facing this situation very often. We use Active@ Boot Disk that is very fast and reliable. At first boot with the cd in the server you want to transfer and backup to a network folder your server image. Then at the new XEN server, boot and restore that image to the new server. I hope this help.
