I am using 2 computers and both are running fedora 23. In computer A I have installed ovirt engine 4.0 and in computer B I installed ovirt node 4.0.3 on a virtual machine manager and both the computer are in a same network.
When I login to the engine admin account using web interface, I tried to setup a host, but always gives error as install failed as shown below, any idea whats going wrong here?
Engine Host setup error picture
I thought it might be due to node storage issue, I tried to setup a node shared storage, again it gives error. Can anyone help how to setup a shared storage for node?
Node storage setup issue
in the lower panel you can see a message telling you that it failed to verify power management configuration.
You can see more messages if you'll go to the events tab.
For full details you can check the host installation log.

I have created a Wordpress website locally using the Bitnami installer. Everything was going well and I have managed to finish designing the website until something happened.
I'm not sure if it is in any way related to the issue but my computer automatically installed a Windows update, since then I cannot access the website that I created locally. It says that,
This site can’t be reached
localhost refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
Again, I'm not sure if this has anything to do with the update, because I have already uninstalled the updated and it's still the same. What's also weird is that my Bitnami managers servers aren't running any servers, and actually there are no servers under it at all.
I am confused and lost as to how this happened and what's the solution for this. I would appreciate any help or pointed anyone can give me. Please see attached Photos.
This is the initial message when I try to access the website
Clicking on the go to application and open my phpadmin doesn't do or open anything
There are no servers
There are no events
Bitnami Engineer here,
If the Bitnami manager doesn't show the services is because they are not installed in the server or they got renamed during the upgrade process. Let's try to reinstall the services again.
First of all, you will need open your installation directory and double-click on the use_wordpress.bat file. That will open the command prompt in Windows
Run the remove command
serviceinstall.bat REMOVE
If the console is closed, open it again and run the install command
serviceinstall.bat INSTALL
Check if the services are now up and running in the Bitnami Manager tool
I've recently moved a Virtual machine from a server to another one.
Both the servers are running Windows Server 2012 R2 as the guest host.
The generation 2 VM run almost perfectly, but it doesn't recognize the network adapter.
Integration services are updated (if I try to re-install it it says they are already updated and doesn't let me repair it).
On device manager I see the exclamation mark left to the adapter.
If I let it search for drivers in C:\Windows it says that the "Network adapter for Hyper-V" is found, but it isn't digitally signed, so it won't be installed.
Anyone could help me making this adapter work?
I couldn't figure out how to remove and re-install integration services either...
Ok, I found a solution.
I had to Disable Driver Signature Enforcement in the advanced boot options.
I have several servers running centOS 6 and centOS 7. I am working in an inventory system, and for that I am using ohai, which is installed in all the machines.
When I do ssh myuser#myserver.com ohai it returns a json object with all the information but the network section empty.
However, if I ssh into the server and I run ohai I get the proper network attributes.
Someone has any idea what can be happening? Thanks!
I solved, the problem was that ohai needs root rights to check the nics properties.
I have installed windows phone 8 SDK and tried running a simple app which embeds a WebBrowser on a page. When I try to run the app in emulator the emulator does not get internet connection. It displays an error message saying "You don't have permission to modify internal Hyper-V network adapter settings required to run the emulator". Im sure my login has admin permissions. My machine is 64bit, hyper v is enabled and Hyper v manager is running, hardware virtualization is enabled in the BIOS settings, DHCP is enabled and its connected to a wired network. I have checked all the system requirements. What ever I do it keeps on giving the same error message. I setup everything in a different machine and tried running the app in that machine. The same error message is displayed in the that machine also. Can anyone tell me how to get it working.
DHCP is enabled and its connected to a wired network
Can you run ipconfig /all on your host machine and post it here please?
seems you have problem with your DHCP or maybe multiple DHCP and conflict.
You need to add your user account as a member of the "Hyper-V Administrators" group on the machine.
Detailed steps:
Hit Windows key + Q and search for "local users and groups". Change the search scope to "Settings". Click "Edit local users and groups".
Expand the "Groups" section. Right-click on "Hyper-V Administrators" and select "Add to group".
Add your user account.
Some connection tools on the host can have negative effects when used with the emulator; I found having cisco VPN client installed on the host prevented the emulator from finding the internet. Other VPN clients may have similar side-effects. I simply uninstalled cisco (the inbuilt windows VPN is fine for what I need) and it worked perfectly.
I've also seen problems where it won't find the internet after the host has been suspended / resumed. In that scenario, it turned out to be bad network drivers. I installed a dedicated Intel NIC (rather than the on-board NIC on the motherboard) - problem solved.
Basically, Hyper-V is a bit fussy.
try refreshing the hyper-v by unchecking and then checking it again,this worked for me.
Steps:
1.control panel>>programs>>Programs and features>>turn windows features on and off>>hyper-v
2.uncheck it and restart the pc.
3.again go to control panel an check hyper-v and restart the pc again.
the try to run the emulator,should work..
another possible reason is that you did not start vs2013 as admin
Since yesterday I can't connect through ssh to all of my Debian wheezy instances on my google cloud. I can connect only through the web console. When the web console tries to negotiate the session, there's a message telling me to update the Linux guest environment. But for wheezy, there is no Linux guest environment package.
Do you have any idea to resolve this issue ?
Debian 7 images were deprecated a while a go and as there are no update packages for the Guest Environment, the best approach would be to migrate to Debian 8 or 9.
To access your VMs you might try one of the following options:
1) According to this public issue the old guest environment still work with deprecated keys. If you have an SSH client configured with an old private key, you might still have access to your VMs through it.
2) Accessing the VM via the serial console
3) Mounting, as secondary, the original disk or a copy of it in a VM you do have access to. The steps are very similar to the section “Inspect an instance without shutting it down” on this document". That would allow you to recover your data.
