Linux Integration Service Version 3.5 installed and it shows "Network Degraded"

In my Windows 2012 R2 , all my Linux virtual machines show "network degraded" in the Hyper-V manager.
I installed the 3.5 version although the Fedora 20 kernel already comes with some hyper-v modules, looking to get rid of the message. I did not succeed, in fact, I am not shore if my new 3.5 modules are bring used or not.
I type
modinfo hv_vmbus

Can anybody tell me if I am using the latest modules, and if not, how can I make sure they do load?

[Forum FAQ] How to upgrade the Linux Integration Service

Symptom
When you move a Linux guest virtual machine from the legacy system to Windows Server 2012 R2 Hyper-V host, you may face the incompatibility issues. The most common problems are that the mouse pointer maybe a little inaccuracies, the guest VM cannot use the
dynamic memory.
Cause
The cause may be that the integration service not compatible with the Windows Server 2012 R2 Hyper-V host.
Solution
We need to upgrade the integration service to at least version 3.5.
In this demo, we use the CentOS 5.8_x86_x64.
You can refer to the following steps to perform the upgrading.
1. Before install the Integration service you can use the following command to check the version of the installed Integration service. (Figure 1)
#su root
#/sbin/modinfo hv_vmbus
Figure 1: check the version of the installed Integration service
2. Download the Integration Service 3.5 image from here.
http://www.microsoft.com/en-us/download/details.aspx?id=41554
3. Insert the Integration Service 3.5 image.
a. Open Hyper-V Linux guest VM console.
b. Click-> Media->DVD Drive-> Specific the Integration service image location, insert Disk.
4. Mount the image.
If automount is enable, the Integration service image will be mounted automatically. If not, please use the following command to mount the image. (Figure 2)
#mount /dev/cdrom /media
Figure 2: Mount the image
After that, we can see the image content. (Figure 3)
Figure 3: Imange content
5. Upgrade the integration service.
Use the following command locate to the current Linux Distribution Directory. In this example, we select the RHEL58. (Figure 4)
#cd RHEL58
#./upgraee.sh
Figure 4: Locate the Linux Distribution Directory
When you see the message, "Linux Integration Service for Hyper-V has been upgraded. Please reboot your system", it means the upgrading is finished.
6. Reboot your Linux system. (Figure 5)
Figure 5: Reboot the system
7. Confirm the upgrading.
After Linux boots up, use the following command to check if the upgrading is succeed. (Figure 6)
#/sbin/modinfo hv_vmbus
Figure 6: Verify the upgrading.

HT1349 I have multiple versions of Outlook installed, and the icloud calendar won't work, how do I correct this?

I have multiple versions of Outlook installed and icloud won't work, how do I correct this?

We mananged to resolve this exact issue on a machine recently that was running MS Office Home and Business 2010. However a copy of MS Office 2000 was also installed (for legacy reasons re Access 2000) and it was this causing the issue. We used Programs & Features to 'Change' the Office 2000 installation to 'Add/Remove' features and de-selected Outlook in here. This prompted a reboot and the issue was subsequently fixed.
Please note this did not remove the Outlook 2010 that was installed (and in use), but be careful to have a backup of your Outlook as your mileage may vary.

In Order to Configure TCP/IP, You Must Install and Enable a Network Adapter Card

I get this message when I try to TCP/IP settings in any network card.
"In Order to Configure TCP/IP, You Must Install and Enable a Network Adapter Card"
What I have tried:
1. Removed card, did not click on "Remove driver". Then re-scanned in device manager. This usually leads to the network card showing up with a yellow exclamation mark, and I can not get it work again (have to use system restore).
2. Removed card, deinstalled driver, re-installed driver.
3. Rebooted a thousand times.
4. Used the Lenovo drivers.
5. Used the Intel drivers.
Doesn't matter what I do, I'm stuck with yellow exclamation marks in the end for the LAN and WLAN card, with not hope to repair them.
Driver version for the Intel 82579LM is 12.9.15.0
Driver version for the centrino advanced-n 6205 is 15.10.4.2
I'd really like some help on how to fix this so I'm able to configure my network manually.

For clarity, as your machine MTM number lists it with another type of WLAN adapter, and apparently, therein lies your problem.

Current version of integration services on Hyper V host and ugrading versions on VM's

Greetings!
I am looking for where the latest version number of integration services is posted, so I may verify what it should be. I am able to query using powershell the vm's on the hosts and get a return of the current version installed. However, I seem to be
unable to find out the current version of IS on the hosts themselves. How do I get this information?

With all current releases of Hyper-V:
When you patch your Hyper-V Server and reboot, the vmguest.iso is generated dynamically to match the release of the Hyper-V Server.
This is historic and was designed to ensure compatibility of the ICs in the VM with the Services of the host.
That said, only Hyper-V 2012 R2 can give you the 'latest' integration components, but they might not function well if VMs are moved to older versions of Hyper-V. That is why 2012 R2 in a VM is 'not supported' on Hyper-V 2008 R2 or 2008 (for example).
In the future Integration Components will be through Windows Update (if your Hyper-V Server is 'Windows 10" or later):

How to set up Bonding on CentOS 6.2 with Linux Integration Services 3.4

Having a hard time setting up bonding to work on a vm running CentOS 6.2. LinuxICv34.iso is installed. Using three network adapters.
Prior to os install I configured the three Network Adapters with the following settings:
***Via Virtual Switch Manager:
Connection Type: External Network, Allow management os to share network adapter
VLAN ID: Unchecked
SR-IOV: Unchecked (Unsupported on host)
Extensions: MS NDIS Capture = Unchecked | MS Windows Filtering Platform = Checked
***Via VM Settings:
For all adapters:
VLAN ID and Bandwidth Management is unchecked.
In Hardware Acceleration, Enable virtual machine queue is checked, Enable IPsec task offloading is checked, and maximum number is 4096. Additionally, Enable SR-IOV is unchecked.
In Advanced Features, a Static Mac address is assigned and Enable Mac address spoofing is checked, DHCP Guard is unchecked, Router guard is unchecked, Port mirroring is None, and NIC Teaming is checked.
Mac Address for each Adapter:
Network Adapter 1: 00:25:0D:20:20:1A
Network Adapter 2: 00:25:0D:20:20:1B
Network Adapter 3: 00:25:0D:20:20:1C
After the os and LinuxICv34.iso was installed, I set up networking access on eth0 by making the following changes:
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
HWADDR="00:25:0D:20:20:1A"
NM_CONTROLLED="no"
ONBOOT="yes"
BOOTPROTO="static"
IPADDR="10.1.1.110"
NETMASK="255.255.255.0"
GATEWAY="10.1.1.100"
DNS1="10.1.1.105"
DNS2="10.1.1.106"
Then:
vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=MyCentOS6.MyActiveDirectoryDomain
GATEWAY=10.1.1.100
and finally:
vi /etc/resolv.conf
nameserver 10.1.1.105
nameserver 10.1.1.106
I entered service network restart and was able to ping google.com so I then moved on to setting up eth1, eth2, and bond0.
DEVICE="eth1"
HWADDR="00:25:0D:20:20:1B"
NM_CONTROLLED="no"
ONBOOT="yes"
MASTER="bond0"
SLAVE="yes"
USERCTL="no"
DEVICE="eth2"
HWADDR="00:25:0D:20:20:1C"
NM_CONTROLLED="no"
ONBOOT="yes"
MASTER="bond0"
SLAVE="yes"
USERCTL="no"
DEVICE="bond0"
USERCTL="no"
BOOTPROTO="none"
ONBOOT="yes"
IPADDR="10.1.1.110"
NETMASK="255.255.255.0"
BONDING_OPTS="miimon=100 mode=balance-alb"
TYPE="Bonding"
I then went back into eth0 and changed it to:
DEVICE="eth0"
HWADDR="00:25:0D:20:20:1A"
NM_CONTROLLED="no"
ONBOOT="yes"
#BOOTPROTO="static"
#IPADDR="10.1.1.110"
#NETMASK="255.255.255.0"
#GATEWAY="10.1.1.100"
#DNS1="10.1.1.105"
#DNS2="10.1.1.106"
MASTER="bond0"
SLAVE="yes"
USERCTL="no"
Next I added file /etc/modprobe.d/bonding.conf per CentOS 6 instructions, and wrote the following line on the file:
alias bond0 bonding
I then entered service network restart and expected everything to work, but instead received these error messages:
ADDRCONF(NETDEV_UP): bond0: link is not ready
bonding: bond0: Error: dev_set_mac_address of dev eth0 failed! ALB mode requires that the base driver support setting the hw address also when the network device's interface is open
bonding: bond0: Error: dev_set_mac_address of dev eth1 failed! ALB mode requires that the base driver support setting the hw address also when the network device's interface is open
bonding: bond0: Error: dev_set_mac_address of dev eth2 failed! ALB mode requires that the base driver support setting the hw address also when the network device's interface is open
I have tried commenting out the mac addresses, USERCTL=no and NM_CONTROLLED=no in the ifcfg files but that hasn't helped.
I'm running out of ideas... Can anyone give me some tips?
Much appreciated~

Hello ECase,
i known my answer is probably too late but maybe it can help others who are having the same difficulties. My setup looks almost like yours and I did the same steps as you did. Unfortunately with exactly the same results.
What helped in my case was to change the teaming mode.
These are the modes available in CentOS:
mode=0 (Balance-rr) –
This mode provides load balancing and fault tolerance.
mode=1 (active-backup) –
This mode provides fault tolerance.
mode=2 (balance-xor) –
This mode provides load balancing and fault tolerance.
mode=3 (broadcast) –
This mode provides fault tolerance.
mode=4 (802.3ad) –
This mode provides load balancing and fault tolerance.
mode=5 (balance-tlb) –
Prerequisite: Ethtool support in the base drivers for retrieving the speed of each slave.
mode=6 (balance-alb) –
Prerequisite: Ethtool support in the base drivers for retrieving the speed of each slave.
Mode 0 -4 worked great while mode 5 and 6 don't work at all. So if you try bonding on a CentOS guest in Hyper-V keep mode between 0 and 4

How can I have Firefox 4.0 and a 64 bit version of Minefield installed and make them use separate profile folders?-thanks

I have been using Minefield, the beta version of Firefox 4 , in a 64 bit version. Since the final Firefox 4.0 doesn't seem to have a 64 bit version, I want to keep Minefield, but still would like to try Firefox 4.0. FF4 uses after installation automatically the Minefield profile folder, which leads to problems , mainly because both browsers are not compatible with the same versions of Add-ons. How can I keep them both but make each use its own profile folder?

Thanks. I tried this and it actually works for the desktops shortcuts but when I pin the modified shortcut to the task bar and try to start either of the two firefox versions from there, the profile manager shows up and asks which profile I wanna use.
Is there a way to fix this?

Detection Office 2010 Service Pack 2 - Slipstreamed Install and WSUS rebuild

Hi,
at a customer of us the WSUS infrastructure had some problems and after some investigation the WSUS infrastructure was built up from scratch. We do have one WSUS Server which syncs with Microsoft and two downstream servers. After rebuild the WSUS infrastructure
we do see one issue:
Many clients were deployed with Office 2010 SP2 slipstreamed. Now the WSUS tells us for the Office 2010 Service Pack 2 Update (KB2687455) that it is missing on the clients.
Is this a normal behaviour or is there an issue with the WSUS detection of the Service Pack? How can I see which updates a client reports to WSUS as installed while connecting with the new WSUS Server? I've tried to figure that out within the WindowsUpdateLog.log
file but without success.
Any ideas are very appreciated.
Peter Forster | MVP Virtual Machine 2002-2011 | Austria |

but wouldn't that cause SP2 to install again (or even downloaded to the client?)
Maybe.
Probably.
If the "SP2 slipstream" was incomplete, or additional Office modules were added post-image, then the service pack needs to be reapplied. The key here is understanding how Office 2010 SP2 is different from other Office service packs in history.

Multiple Versions of Excel installed and using BPC

Is it possible to have Excel 2003 and 2007 installed on a users desktop and have BPC work properly? We have some users that want to retain 2003 on their computers but are experiencing issues.

I know from working with our consultant that it isn't recommended but this group has some software that requires it to have 2003 available for at least a while longer.
The specific issue that prompted my question:
User has the Log on/ Log off button when in Excel 2003 but does not have it available in 2007. She wants to create templates using 2007 but cannot access it.
This is a new group of users for us and they are the only group that wants to maintain both versions. Since we are seeing this issue and we know it isn't recommended, I am trying to get in front of the issue to identify what other problems may arise and if there is a way around it?
Thanks,

G4 Won't Boot after Tiger install and Belkin USB Network Adapter install.

I'm sure this would apply to my G5 as well.
I installed Tiger on my G4 and it restarted and opened to desktop. Great!
Next, installed software drivers from Belkin USB Network Adapter.
Restarted computer,
Screen has firmware 'like" look asking me to type mac_boot.
I do this and the next screen is all grey with two small purple folders in the corner. I believe one was flashing!
Nothing happens just stays there.
How can I get back to normal boot mode?

tigerswim, welcome to Apple Discussions.
Did you already have Tiger installed or did you have Panther 10.3 installed? Tiger is not a free upgrade; you have to buy it & then update (for free) using the download updates from Apple. Also, you have to use a universal/retail install DVD (or CDs) to install Tiger. You cannot use the install DVD from another model Mac.

Blackberry messenger installed and doesnt show up!

Hi,
I upgraded my Blackberry with OS 5.0 and installed blackberry messenger! It doesn't show up on my phone?
Can anyone tell me where can I find that downloaded one? And how to run it?

I assume it's not gone into your Downloads folder?
You can assign applications to whatever folder on your menu screen you like, and I suspect it maybe in there.
