Unable to attach second disk on CentOS 7 VM
Hi all ACS members.
Did anyone face in the past any issue while attaching a second volume on a CentOS7 VM? I receive the following message:
"Failed to attach volume testVolume5 to VM CentOS7VM; Failed to attach volume for uuid: aa763fd8-02dc-42a1-bfe1-4e44201e487f due to You attempted an operation on a VM which requires PV drivers to be installed but the drivers were not detected.”
I tried the following solution:
- yum install centos-release-xen
- yum update
- reboot
But again it didn’t work (essentially, booting with 3.18 kernel instead of 3.10). Any ideas? Our CS version is 4.6 together with XenServer 6.5
With CentOS 6.7 everything works fine.
Kind Regards
Stavros

I believe after you install the drivers you have to change the OS type for
your VM. That information is used when creating the VMM. So, you have to
choose a type that indicates to ACS that we can create a “PV” VMM.

You need to mount it, usually from /dev/xvdd
Try: mount /dev/xvdd /mnt

Thank you for the idea Sanjeev.
Tried this already but the iso does not appear in my VM (nor /mnt or /media). I downloaded xen-tools 4.6.2, compiled them and installed them but still can’t manage to mount the second volume.
Any other software package that could help solve this problem?
Kind Regards

Xen-tools include the required PV drivers and we don't have to download anything for this. Try attach ISO option on a vm from CS UI and you will see xen-tools iso in the drop down list.

Thanks for the idea. Do the xen-tools include the required PV drivers?
I know that there is no official rpm of xen-tools so I need to download them and install them manually, correct?

Install xentools.
I have no idea what centos-release-xen is, but apparently it is not enough
for your hypervisors
