i have 2 hosts which is hosting my servers in my org. i m thinking to create daily backup plan for hyper-v guests.
can i use Windows Server back or i can use any other tools. i want to take backup of my servers in running mode i don't want to shutdown them for backup region is this possible.
Currently i have configure windows image backup in hyper-v guest for daily backup in case my hyper-v guest fails can i recovery it via windws image backup which is running daily in side the guest.
I have 2 hyper-v hosts bot are running server 2008 r2 with Sp1. recently we moved our application server to another host . i have export guest first
then while copying via network its very very slow. takes neare about 7 hours to copy via network guest size is only 33 GB only.
need help :)

Hi,
Kindly help Can we install Red Hat Linux 5.5 & 5.6 64bit OS on Windows Server 2012 Hyper-V.

Running Win2008 R2 HyperV. Click on a running VM and select Shutdown option. Get error saying that "Can't find shutdown integration component."
What does this error indicate. How do I resolve it?
thanks
Would like to apply Microsoft updates to the host server but this will most assuredly require a reboot. Some of the guest VM's are safe to shutdown while others may lose state upon shutdown. Is it safe to pause a running VM for a reboot and unpause after reboot?
Environment is as follows:
Dell PowerEdge T320 (new), 24 GB RAM, 2 Broadcom NetXtreme NICs (LOM) @ 1 Gbps. Infrastructure is also using 1 Gbps switch and client PCs are connected there.
Windows Server 2012, Hyper-V role installed. Just one VM running now, running SQL Server. A second VM created for testing purposes, but not running.
Network throughput from the VM is very poor, typically about 3-5 MB/sec when copying a large file, but sometimes below 1 MB/sec. SQL Server network performance is so poor that apps running from a client are not usable. Running the same app logged directly to the VM is very fast, so it's not the VM itself or SQL on that VM.
Network performance from the host is excellent - can copy large files at above 100 MB/sec, essentially saturating the gigabit backbone. It's VM network performance through the virtual switch/NIC to other systems in the network that's bad.
Existing Hyper-V servers (to be replaced) running Server 2008 do not exhibit this issue.
We've tested file transfers between two VMs connected to the virtual switch on the T320. Runs fine, > 100 MB/sec. Running SQL apps from a second VM connected to the virtual switch has excellent performance.
Everything points to the transition from the virtual switch to the NIC to the internal subnet. That path is very slow.
Any suggestions?
Windows Server 2012 - Every day around 12:30 AM the VMMS service shuts down and I get event 14090 "Hyper-V Virtual Machine Management service is shutting down while some virtual machines are running. All running virtual machines will remain running with no management access."
It is being shutdown by the Service Control Manager I can see it in the System event log. Although it does not get started back up.
Dell R510 PERC H700: 8 virtual disks in total. System drive\OS on RAID1, other 7 VD on 4 SAS 600GB as RAID10
Host has 48Gb ram and is running dual Xeon E5645 CPU's
Read Policy: Adaptive Read Ahead
Write Policy: Write Back
Disk Cache Pol: Disabled
OS: W2K8 R2 ENT, Hyper-V + failover clustering
Each VM hosted in separate volume on RAID 10, SIOS DataKeeper Cluster Edition replicating the 7 volumes to two identical R510's
VM's: One Exchange 2010, one SQL2005, Citrix Server, File and Print (Os mixes of W2K8 and W2K3 64 Bit) plus a couple of other application servers.
Problem:
I am seeing very high average disk queue lengths in all the 7 VM's (maxing at 100 in performance monitor) whenever I try and do large(ish) file transfers (2Gb plus) whereas if I file transfer between the hyper-v hosts on their RAID1 disks and outside of the hypervisor layer, I see pretty respectable throughput and no maxing out on average queue lengths
Other symptoms: Exchange VM slows right down if anyone emails attachments of say +7Mb.
File and Print Server VM, long time to enumerate folder structures etc...
I've tried updating BIOS, RAID f/ware Broadcom network adapters (against my better judgement I've got a Broadcom LACP team upto my switch for VM LAN access). I'm also seeing pretty sluggish throughput with IPERF from other LAN computers into the Hyper-V VM's
Edited to add: have migrated one VM to a Hyper-V node in the cluster with no other VM's running, give the VM a load more RAM and still seeing same problem
Kind of running out of ideas here, any help appreciated
I received this problem, please find below,
The OpsMgr Connector could not connect to SCOM.MCYCD.UAE.GOV.AE:5723. The error code is 10061L(No connection could be made because the target machine actively refused it.
). Please verify there is network connectivity, the server is running and has registered it's listening port, and there are no firewalls blocking traffic to the destination
please advise,
Hi,
I read many documents about Windows 2012 Server/Hyper-V networking, but not know best practice for full redundant hardware.
I prepare setup 3 node cluster on WS2012/Hyper-V3 and I have full redundant infrastructure.
Each server have 10 NIC,
NIC1 is connected to iSCSI_Switch1/ NIC2 is connected to iSCSI_Switch2
NIC3..6 is connected to IP_Switch1/ NIC7..10 is connected to iSCSI_Switch2
and for cluster I have:
iSCSI network (I set IP 10.10.10.1 for NIC1 and 10.10.10.2 for NIC and configure MPIO) - OK
Management network (NIC3+NIC7 in team) - OK
Live Migration Network (NIC4+NIC8 in team) - OK
Heartbeat/CSV Network (NIC5+NIC9 in team) - ?Is recomended this network in team ?
VM Network (NIC6+NIC10) in team ???, ports on switches for this NICs is trunk ports, team is not compatible with SR-IOV ???
How configure VM network redundant and with SR-IOV support for this cluster setup ?
In this network is many VMs in diferent VLANs.
Thanks,

I am having a strange issue with Hyper-V and a guest. Here is the setup
Server 2008R2 on the host with hyper-v role and 4 guests all of which are running 2008R2, All are fully updated with windows update. so whats happening is when I am running a backup of the host drive which contains the vhd files one guest is loosing connection in a very strange way. During VSS creation the host looses icmp traffic to one guest however at the same time the guest can continue to ping the host ( I know this is strange) The other guests all seem to lose the connection the the guest the same as the host. it usually drops for about 15 icmp packets and then comes back very strange.
I have tried this patch http://support.microsoft.com/kb/2263829 however it was already installed and i'm really starting to tear my hairout. As the guest that is loosing it's connection is a server for a line of business app which has file shares and sql server and the app totally die's every time this happens and I'm thinking this is happing when the server is under a bit of load. can anyone suggest anything which may help.
all the VM's and the host are in the same virtual network
Dear all,
I have a big problem with my hyper-v server and network card. I've found a lot of topic around this question but none of them helped me.
I have a Win 2008 R2 Server with only Hyper-V installed. I have 3 NIC , one is reserved to the host management and the others two are reserved for virtual machine .
All NIC are Intel, one is integrated on the Intel motherboard and the others are Intel Gigabit ET Dual port .
Before installing the role of Hyper-V all NIC worked perfectly with speed around 1Gb (file transfer average 90 MB/Sec, of course I have a Gigabit LAN) .
After Hyper-V install, the host system is going very slow and the network file transfer using the dedicated NIC is about ten time slower (9-10MB /sec) . Same problem with all VM off and also if I remove all VM !
I tried all of suggestion found in old post (disabling TCP checksum / offload ...) but nothing happens.
What is really strange is that by removing all network card all the Host operating system seems to improve the speed... but, of course, I can't use my LAN :(
I need help because every night I must make a full backup of Virtual hard disk from the host to a backup server in my lan.
My configuration:
- Server Win 2008 R2 SP1 with Hyper-V and no others role
- 2 Virtual Machine (one Win 2008 R2 and one Win 7 Ultimate)
- NAS Linux (access via SMB with no problem)
- Various Windows 7 Pro client
Thanks in advance to everybody,

Hi there. I need to move a bunch of VMs from one SAN to another, but to keep them on the same host.
I'm running Hyper-V on windows 2008 R2. I reckon the best way to go about this is the old export/import method, but I'd got a few questions.
1. If I export, then import again, how do I change the location of the VM? when I export and import again, the VM appears to have moved to the C drive of the host, even after I've move the exported files to the new SAN before importing! Any ideas?
2. I then copied the files over to the new SAN and manually changed the file path of the VM and the VHDs in the properties of the VM, but I cannot delete the old VM as it's in use still.
Any help would be appreciated. thanks,
Jonny
We are mapping out the best solution for a client who has a single Hyper-V Host running three VMs, so that Windows Updates and other maintenance tasks can be completed. Based upon some updates requirements to have the running VM guests shutdown (not in saved state) a windows for scheduled maintenance can be agreed upon some time early on Sunday, so need to have an automated solution instead of having a tech logon.
What I am thinking is:
What are others doing and how can I achieve above and any thoughts on plan above?
