Guest Agent Console
by Hari Prasanth Loganathan
Hi Team,
A Quick question,
As per this document (
https://www.ovirt.org/documentation/vmm-guide/chap-Installing_Linux_Virtu...),
If I Install the common package - ovirt-engine-guest-agent-common using the
apt-get / yum
install ovirt-engine-guest-agent-common
*Will it also install the drivers mentioned in it?*
virtio-net, virtio-block, virtio-scsi, virtio-serial, virtio-baloon, qxl

Disk Statistics API in Ovirt
by Hari Prasanth Loganathan
Hi Team,
We are using the following API to collect the disk statistics,
https://X.X.X.2/ovirt-engine/api/
*disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics*
<https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3db...>
I found one issue in the disk statistics. In case If the Virtual Machine
has this disk (*2331bad7-71ec-4fad-95bb-2b3449f3dbda*) attached to it and I
perform some read / write operation in the VM and it increases the
corresponding disk level Read data rate / Write data rate /
disk.read.latency / disk.write.latency.
*Example*, I received the following values for this disk, But the problem
is even when I bring down the VM still the last known value is received
continuously.
*Is it a known issue Or any workaround is available? *
*Expected : All values should go to Zero*
*Actual : All values retains the last known values when the VM was in UP
state. *

Windows VMs won't boot in debug mode
by Andrew X
Hi Everyone,
I've been having problems getting Windows 10 VMs to boot in debug mode
after turning on debugging over network (steps below). Also, device manager
in Windows is not showing the processors' node which might be related (same
reason why Windows is refusing to boot in debug mode?). I don't have any of
these problems when I use generic KVM or Proxmox KVM.
To turn on debugging in Windows, I do the follwoing from an admin terminal
window:
bcdedit /debug on
bcdedit /dbgsettings net hostip:a.b.c.d port:p key:1.2.3.4
Any help will be appreciated,
Thanks,
Andrew

Disk Statistics API in oVirt
by Hari Prasanth Loganathan
Hi Team,
We are using the following API to collect the disk statistics,
https://X.X.X.2/ovirt-engine/api/
*disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics*
<https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3db...>
I found one issue in the disk statistics. In case If the Virtual Machine
has this disk (*2331bad7-71ec-4fad-95bb-2b3449f3dbda*) attached to it and I
perform some read / write operation in the VM and it increases the
corresponding disk level Read data rate / Write data rate /
disk.read.latency / disk.write.latency.
*Example*, I received the following values for this disk, But the problem
is even when I bring down the VM still the last known value is received
continuously.
*Is it a known issue Or any workaround is available? *
*Expected : All values should go to Zero*
*Actual : All values retains the last known values when the VM was in UP
state. *

Network storage traffic
by John Nguyen
Hello,
This is more out of curiosity, I was wondering during a migration or
import/export does all the storage traffic goes through the SPM server?
Thanks

Jump from a disk to its storage domain from VM disk
by Gianluca Cecchi
Hello,
currently on 4.2.3 I can
- Select Storage --> Disks
- Select disk link in the line (in the "Alias" column)
- In the new disk page select "Storage" tab
and I can see the related Domain Name and its information (eg free space if
I want to extend the disk)
--> it would be nice to have a "link" on domain name so that you can
directly jump to
Storage --> Domains --> Domain Name
It would be nice to have similar behavior also directly starting from
Compute --> Virtual Machines
Select VM --> Disks
Select disk
Here I can select "edit" and then in the edit window I can see information
about storage domain between the other fields.
It would be nice to have a pointer to directly go to the storage domain
containing that disk.
