[ovirt-users] Re: Ceph cluster on oVirt Guests

2019-10-18 Thread Anantha Raghava

Hi,

It appears it is. We tested it on the physical hardware with same CentOS 
7 and same release of Ceph and it works like a charm. We also tried it 
with VMWare, and it works perfect. Of course, on VMWare we have to 
install open-VM-Tools in place of VMWare Guest tools. But with 
ovirt-guest-tools, we get error and open-vm-tools appears not designed 
for oVirt.


Thanks & regards,

Anantha Raghava

Hi,

In version 4.0.2, Live Migration was supported with Open Virtual Switch 
and was informed that migration support with OVS will be included in 
version 4.0.4. Is live migration supported with OVS in current version 
that is 4.0.4?

[ovirt-users] RDP as default console for Windows VM

Hi,

In the past, we could set RDP as default console for Windows VM. VMs 
used to reboot once we set RDP under console options & become default 
for all users. In the new versions I am unable to achieve the same result.


Is there a way to set RDP as default Console for Windows VM?

[ovirt-users] Install CiscoISE VM on oVirt

2018-06-12 Thread Anantha Raghava
Hi,

I am not sure whether I should write it here. However the documents
referred to specifies that I have change something in BIOS of VM & there is
no way to get access to BIOS. Hence I am writing here.

I am trying to install Cisco ISE in a VM on oVirt. The installation process
halts reporting "Unsupported Hardware Found. The Cisco UDI (Unique Device
Identifier) found on this appliance does not match with supported UDI of
the product being Installed. Exiting installation"

However it works perfectly on VMWare ESXi, VMWare Workstation and VMWare
Fusion. In fact I tested this in VMWare Workstation and VMWare Fusion. The
same ISO file throws above error.

Cisco ISE is based on RHEL 7 and it is hardened.

Has any one attempted to install Cisco ISE in oVirt? Any one throw some
light?

My oVirt Version 4.2.3 and Hosts are on 4.1.9


Thanks & regards,

Re: [ovirt-users] oVirt virtio drivers for fedora 5

2017-12-31 Thread Anantha Raghava

Hello Sergey,

Your suggestion worked Instead of extending the disks, we added the 
third IDE disk with about 500 GB, created the required partitions, mount 
points and just synchronised the date from physical server to all these 
mount points using DD command. Post the completion of synchronization 
process, we modified the fstab and the VM went live.


Now all well.

Thanks for your suggestion and WISH YOU & THE LIST A VERY HAPPY NEW YEAR.

Re: [ovirt-users] oVirt virtio drivers for fedora 5

Maybe you can make this two disks larger, make more extended 
partitions on them and move partitions from disks 3 and 4 to this two 
and modify fstab accordingly?
Or if you don't need separate mount points you can extend space on / 
and move data to / filesystem tree and remove fstab entries,

and use only 1 virtual disk, if it's acceptable.
All this can be done from modern OS, you can connect all 4 disks via 
virtio drivers, connect 5th disk, move data to it, install fedora5 
bootloader,

modify fstab and than reattach to original vm via IDE.

Hi,
We have converted a very old fedora 5 server to run on oVirt. However, 
since the Fedora 5 does not have virtio drivers, or virtio-scsi 
drivers, the disks are connected to virtual IDE interface. The problem 
here is on a single IDE interface, we cannot connect more than 2 
disks. But the old converted server had 4 disks on 2 IDE controllers.
First question is can we add one more virtual IDE Controller to the 
VM? If yes, please share the procedure. Or whether any one can share 
the proper virtio or virtio scsi for fedora 5 OS drivers so that we 
can get other two inactive disks working.

Unfortunately we cannot upgrade from Fedora 5 at the moment.
Await your inputs.

Neither are possible. Does the Fedora have an iSCSI initiator support 
perhaps? You can expose those disk via different VMs to that VM - but 
still it might look different to the OS.

(We don't even support such an old OS - but if it works, great).

[ovirt-users] virt-p2v not recognising Hard Disks of Server

2017-12-16 Thread Anantha Raghava

Hello,

I am trying to convert a physical server (10 year old hardware with PCI 
LSI Loging / Symbios LSI MegaRAID controller and SCSI drives, RAID 5 
Configuration). Host to be converted has Fedora 5 OS.


I have downloaded the virt-p2v.iso (Cent OS 7.3). I have prepared the 
conversion server. I am able to boot the physical server with 
virt-p2v.iso. I am able to connect to conversion server. But none of the 
Hard Disks are listed to select for conversion.


I opine, probably it is something to do with SCSI / RAID Card drivers.

Is there a way I can get these drivers into virt-p2v.iso? Any 
suggestions to get this task to completion?


Thanks in advance.

[ovirt-users] Killing Zombie or hungTasks

2017-10-03 Thread Anantha Raghava

Hi,

We attempted to import a VM from export domain and that failed for some 
reason. However the import task or the activity never ended in spite of 
throwing an error. Even after 4 full days, on the VM an Hour glass was 
shown and it kept reporting, hung task.


Finally we had to run engine-update, that removed Zombie tasks and VM 
started showing as DOWN and we could remove the VM.


I believe, this is not the right process to remove the zombie tasks or 
hung tasks. Is there a better method without running "engine-update"?

Re: [ovirt-users] Change CD Issue

Hi,

You pointed out right. It is a specif issue with our second host 
(Host-2). For all VMs running on First Host (Host-1), Change CD works 
fine. It throws error for all VMs running on Second Host (Host-2). It 
has no relation with Host being SPM.


Looks like some issue with our second host (Host-2) specifically.

We migrated one VM from Second Host to First Host and Change CD works 
properly.


But how do we check what the error is? How do we fix it?

[ovirt-users] Kill a long running task in oVirt 4.0.5

2017-04-21 Thread Anantha Raghava

Hi,

We are using oVirt 4.0.5. I tried to import an exported VM into the 
oVirt infrastructure. The process started and from last 24 hrs, it is 
still running and I am unable to kill it either.


I tried to use "stopTask" command, but host is reporting "stopTask" 
command is available. How do we kill the long running task?

Hi,

I am trying to upgrade my setup from version 4.1.0* to 4.1.1. While the 
yum update "ovirt-*-setup*" worked without any issues, engine-setup 
command is throwing errors. Screen shot is shown below. I even updated 
my CentOS. Yet the same issues continue.


Can someone extend help upgrading the engine version?

Re: [ovirt-users] oVirt Nodes Monitoring

2017-03-08 Thread Anantha Raghava

Hi,

You can also monitor by enabling SNMP in Hosts. For this purpose, using 
the MIB, you need to build a Zabbix Template as detailed in the link 
here https://github.com/jensdepuydt/zabbix-ovirt


We are monitoring Version Hosts with CentOS 7 and oVirt 4.0.x using this 
method.


I will share the Zabbix-Template, we have built tomorrow as I, at the 
moment do not have access to my resources.

following command:


semodule -i zabbix_agent_setrlimit.pp

Hi.

How do you guys monitor your hosts with Zabbix ?
I see the oVirt Nodes have snmpd service installed and could be used 
for basic things but ideally, for Zabbix is good to use its agent.


What would be the best way to install its zabbix-agent package and 
make it persistent ? Add its repository to the oVirt-Node in 
/etc/yum.repos.d/ and install it with yum or install using a .rpm 
directly ?

[ovirt-users] Ubuntu VM does not complete reboot cycle without Console Open

2017-03-06 Thread Anantha Raghava

Hi,

I have been observing that Ubuntu Precise VM, if restarted using a 
crontab at a given time, stops at the OS / Kernel Selection screen and 
does not complete the reboot. If we issue the reboot command with 
Console open, the same command works without any issues and the VM boots 
properly. This issue happens only with Ubuntu Precise and not with 
Trusty or Xeniel or even with any of Rehat distributions or CentOS.


Interestingly, it doesn't happen with VMWare ESXi.

I also read somewhere that this issue is with VDSM 3.6 and it seems to 
continue with VDSM 4 as well.


Any suggestions in this regard.

Re: [ovirt-users] Exporting VM as ova

2017-02-12 Thread Anantha Raghava

Hello Arik,

Interesting..

I was thinking that, by converting to OVA appliance, we can release our 
product as appliance that will work on Xen, VMWare or KVM. Now OVA works 
both on Xen and VMWare and both can be interchanged with each other.


Do you mean to say that both Xen and VMWare have written specific 
parsers to convert the disk formats amongst each other.


Xen, I am talking about Citrix Xen.

Thanks Anantha.
That's true only to some extent.
For example, without converting OVA that was generated by VMware using 
virt-v2v oVirt cannot consume it since the VMDK disks format is not 
supported in oVirt. Another example is the OVF representation that 
differs among various virtualization management platforms.
So if you are trying to migrate a VM from oVirt to another platform 
and assume you'll get this out-of-the-box by having an OVA that is 
generated by oVirt, I'm afraid you'll be disappointed in case the 
target platform doesn't support the format of the disks or doesn't 
know how to parse the OVF that is generated by oVirt.
And there may be more use cases for exporting the VM as OVA, that's 
why I'm interested to know what's the goal in this case :)

Anantha, when you say “will not allow us to change anything” what exactly do
you mean?
  

Does it generate the same “unhandled exception” error as when adding disks
or something else?
  

I was able to specify 4 vCPUs consisting of 2 sockets (each with dual core)
and it worked fine.
  
If you specify a disk FIRST and then try to to change the virtual CPU

configuration it will no longer work. Basically if you edit/change/add a disk
and a new window pops up, some stuff that shouldn't have been cleaned up, is
cleaned up and breaks anything that relies on that, like the check to see if
the virtual CPU configuration is valid. A bunch of other stuff as well like
the exception mentioned below.

I don’t know of a function built into oVirt for scheduling snapshots.
If you don’t already you may want to setup an export domain (NFS
based), on separate storage.

Just a reminder: snapshots are not backups and they should only be
kept temporarily. We use this tool for backups:

https://github.com/wefixit-AT/oVirtBackup

It’s not the most efficient as it clones a VM from a snapshot, then
exports the clone – so you’re transferring the same data twice. But it
works for our purposes. We have this running in a cron job.

If anyone has come up with a script that uses the newer API to export
a snapshot directly, please share!

We get the same error when adding a disk while creating the VM (In
Chrome, Firefox, and Safari on OS X Sierra client). This is reportedly
fixed in 4.0.6 per this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1394175

Could someone with 4.0.6 confirm that?

I have few questions.


a. Can we schedule the VM snapshots? If yes, please share the procedure
b. Snapshots are stored on the same storage domain. Can we move them
to another storage domain say NFS domain for additional safety? If,
yes, please share the procedure.

Also, after upgrading to version 4.0.5, at many places, especially
when we are creating a new VM and trying to create a new Disk for the
VM, we keep getting "uncought exception" and the process will not
complete. We have to create a VM, without Disk and then create the
disk separately and attach it to VM.

Is anyone else facing this issue? These sort of issues were not there

Hello Daniel,

Thanks for inputs.

Also, one more problem we observed in 4.0.5. When creating VM, we cannot 
change the CPU, sockets, cores. It will not allow us to change anything. 
We have to save the VM during creation with 1 vCPU. Again, edit VM and

Re: [ovirt-users] Hosts lost the communication with FC Storage Domains

2016-12-09 Thread Anantha Raghava

Hello Nir,

LVM backup & restore...risky, but have no options. Let's try this. VMs 
contain some sensitive data that cannot exist outside these VMs. Even VM 
snapshots are on the same storage. But we did not take a Volume Snapshot 
at the storage level :-(


We will make an attempt & post the results.

to add the same existing LUN as new Domain, it fails to add. It will not
format the LUN as needed to add it as storage domain. Wondering as to why is
this?

Even if some one added the existing LUNs ignoring warning, without realising
danger, how the running VMs continued to work till we shut them down? I can
understand the refusal to start a shutdown VM or failure to migrate from one

I guess that lv data was not affected, only the lvm metadata was destroyed.

When an lv is active, you have access to  certain segments on the pvs
backing the lv. Deleting the lvm metadata should affect running vms.

The data of the vms is probably still on storage and probably can be restored
by using the lvm backup information. You should be able to create a device
mapper device mapped to the same segments on storage as the original
lvs and restore the data, but I never tried to do this.

Hello Yaniv,

I sincerely apologize for pushing you guys.

We have taken the steps suggested by you only to realize that the 
Storage volumes are having NTFS format instead of LVM2!! Hence become 
not accessible. We were able to create new LUNs and add them properly as 
storage domains.


But only surprising part is all running VMs continued even after the 
storage domain and DC going down till such time, we manually shut them 
down. How is this possible?

1. Please upgrade to the latest release first.
2. Please ensure that on the host everything is properly connected,

3. Please ensure no one erased the domain LUNs - are the VMs using it

Hello Didi,

Apart form oVirt-engine, nothing else is running on the server. Engine 
is running on CentOS 7.2 minimal installation. We have 2 hosts, 1 iSCSI 
storage, about 19 VMs and 5 Networks. In this setup oVirt engine is 
running in a separate VM created on VMWare ESXi. In 20 odd days, it 
consumed around 70GB out of 100 GB!!!


In another setup, we have only one host, hosted engine, 9 VMs, 2 
Networks, 1 FC Storage. In about 30 odd days, 100% of available 100 GB 
consumed!! It is in this setup CentOS is not allowing us to loginto 
engine VM as no space to create any temp files on the storage. We have 
ISO Domain created on this engine VM. But that's only about 3 GB in size.


Both setup are not exposed to internet. Hence, any malware is ruled out.

We have observed, the logs are also growing and we have not found that 
logs are not rotating. All logs right from day one are kept intact. 
Nothing in the user files. Because no user is allowed to use this VM.


What else it could be? 100% consumption without even a warning, is very 
strange.

Is it that DWH database and the logs really take so much of space so fast?

Are you sure that DWH database is the only thing using much space? Did you
check disk space usage?

DWH db size depends on the size of your setup - number of
hosts/VMs/disks/NICs/etc.

You can also affect this by configuring granularity and history
length, check e.g.:

https://www.mail-archive.com/search?l=users@ovirt.org=subject:%22Re\%3A+\[ovirt\-users\]+Limit+DWH+database+size%22=newest

http://lists.ovirt.org/pipermail/users/2016-September/042419.html


How do we reduce the disk utilization? This will be a major issue when
compared to other hypervisors management platform.

How do we address this and arrest this super fast disc consumption?

Hi,

engine's console to clear some files as well. When I try to add additional

not managed by oVirt Engine, it cannot extend the storage.

Now the questions are:

1. Is it that enabling advanced DWH on the engine host is the root cause for
100GB of disk getting filled in about 1 month?

2. How do we clear the disk of some unwanted files and extend the space?

3. How do we reset the DWH database to basic?


Note: CentOS 7.2 is not even allowing us to login to console to do any
action. Booting the Hosted Engine VM with Live CD etc., looks like is ruled
out in this case.

Use NFS on each host to export the local disk to your cluster. Ensure 
this is remembered, as when you want to reboot a specific node, you 
have to put the storage into maintenance as well.


I also like to pin each VM using the storage to the node the NFS 
export lives on.

[ovirt-users] Using Local Harddisks on the Host for Storage Domains

2016-10-25 Thread Anantha Raghava

Hello to all,

Can we make use of large hard disk drives on the Hosts for shared 
storage domains?


In our setup we have iSCSI storage on which the primary storage domain 
is created and is being used. On the hosts, we have 1 TB of storage that 
is not used for anything and just going waste. Can we make use of them 
in some manner?

Yes, it is root cause. Active directory usually has anonymous

rather than using a specified MASTER_STORAGE Domain built on iSCSI 
storage. Realising the mistake, I moved the VM's disk from EXPORT_DOMAIN 
to MASTER_STORAGE domain. The engine reported that disk moved 
successfully. When I attempted to start the VM, I am getting error 
"Cannot start VM, related operation is in progress". This error has 
persisted over last 24 Hours!!. I attempted to remove the disk from VM, 
same error appears. When I try to delete disk from MASTER_STORAGE 
Domain, same error appears.


What could have gone wrong in this disk movement?

I am using oVirt 4.0.2 on CentOS 7 and 2 hosts in the cluster are also 
with CentOS 7 base OS on which the Hypervisor is installed.

Hi,

Unfortunately not. Engine log may be there, if it is not rotated 
already. But VDSM logs are not there at all.


I have two more servers of the same configuration. Let me try & simulate 
the same situation.

Hi,

But I have run into a different problem. Yesterday, for some
reason, I had to restart the hosts. But the Hosts never came
online. Hosts were constantly in Non Responsive state. I manually
fenced it, and Vds command timed out.

I found that NIC was down for some reason. I brought it up and
again fenced the hosts. Again the Vds command timed out. I
manually attempted to restart the VDSM service, but host reported
there is no such service. Starting VDSMD service resulted in failure.

Finally, I had to forcefully remove the hosts, reinstalled base
(CentOS 7) on hosts and re-added them to oVirt with the storage
domain intact. All hosts, storage domains went online and all VMs
were intact.

Post reinstallation, I set the Cluster Switch mode to "Legacy" and
tried migration and it worked fine.

I fail to understand what went wrong while rebooting the hosts.

Re: [ovirt-users] Adding iSCSI Storage

2016-08-25 Thread Anantha Raghava

Hello Elad,

Thanks for quick reply. That was really quick.

Your assessment was right. On the iSCSI storage multiple iSCSI 
initiators were disabled. Hence the authorisation error. Once I enabled 
the multiple iSCSI initiator support, the primary storage domain came 
live and DC also went live.


However, I am still confused on iSCSI mutipathing and bonding. Will try 
creating bonds and write back if I get stuck.

vdsm.log had been rotated since, it's too new and doesn't have the

From engine.log [1] it seems that you had an iSCSI authorization

pool. It happened during storage pool creation.


It does seem you've hit 
https://bugzilla.redhat.com/show_bug.cgi?id=1359788 
<https://bugzilla.redhat.com/show_bug.cgi?id=1359788> since you report

The workaround for this is to update the DB and change the domain status.
Or, if possible, I'd suggest to clean the setup and create a new 
data-center.
For first storage domain creation in the new DC, in case it's iSCSI, 
please make sure you provide the correct iSCSI credentials for login 
or use other type of storage (NFS for example).

That is because your libvirt URI is wrong. It has to be 'xen+ssh://...'
not 'ssh://...'.

Does it work if you try: virsh -c 'xen+ssh://root@192.168.1.40'

Re: [ovirt-users] Importing VM from Xen Server 6.5

2016-08-10 Thread Anantha Raghava

Hello Richard / Shahar,

I installed and enabled nc on Xen Server host. Now the " .. sh: nc: 
command not found: Input/output error" is gone. Communication is 
established. However I am still getting two specific errors:


VDSM ovirt_engine command failed: End of file while reading data: : 
Input/Output error


&

Failed to retrieve VMs Information from the external server 
xen+ssh://root@192.168.1.40


I am receiving the same error when I run virsh -c 
xen+ssh://root@192.168.1.40


Screen shot is attached for quick reference.

Is it something to do with firewall / ip tables on xen server or 
libvirtd host?

Yes, you need to install 'nc' on the *target* (Xen) machine.

This is because libvirt's ssh transport uses nc:

This is exactly the error message oVirt engine as well. You can see the

[ovirt-users] Hosted Engine & FC Data Domain

2016-07-25 Thread Anantha Raghava

Hello,

I had recently installed oVirt 4.0.1 Hosted Engine with FC (SAN) Storage.

I could install the oVirt, deploy hosted-engine. But when I accessed the 
Engine Web Admin, I noticed the following:


a. There was no Data Domain. I had to import the FC LUN, on which the 
Hosted Engine's Disk resided into Storage manually. But when I attempted 
to attach the data domain to Data Center, it failed.


b. I ended up removing all configuration, and recreated the FC LUNs. 
This time, I created two LUNs, on one LUN, the Hosted Engine resided. 
This time, first, I had to import the second LUN as master Data Domain 
and add the LUN on which Engine VM resided as just another Data Domain.


Now the questions:

i. Will Hosted Engine not automatically import the hosted_storage as 
master data domain? Why does it throw error when attempted to import and 
attach to DC?


ii. Is it necessary to have another data domain as master data domain, 
before attaching hosted_storage?


iii. How do we change the master data domain from one to another?

[ovirt-users] Importing *.ova appliance

Hi,

How do we import a *.ova appliance in oVirt? Starting 3.6.6, we see this

files, it reports "did not find any VM to import".


Does oVirt still not support importing OVA appliance?

Re: [ovirt-users] Hosted Engine - Storage Domain registration

2016-06-21 Thread Anantha Raghava

Hi,

I was able to map the hosted_storage to default DC. This appeared & got 
attached after I mapped another NFS Share as Master Data Domain. Even 
the HostedEngine VM appeared under Virtual Machines Tab and status was 
set to up.


I could install ovirt guest agent and got all other information reported 
from agent service.


But I noticed that although I have installed CentOS 7.2 in Hosted 
Engine, VM reports it is a Desktop and not a Server. I attempted to 
change these values and also the Clock off set, but received error as 
locked parameters cannot be changed etc. Does the Hosted Engine really 
use a Desktop Profile? Can't we change it?

Hello,

I have not understood clearly whether your were using hosted engine or

I'm asking that because - as Alex knows it - I'm facing this terribly 
slowness since months, and we took a lot a time trying to figure it 
out, to no avail.

We're using 3.6.5 and bare-metal engine.
I triple checked DNS resolution, added (anyway) relevant fqdn in 
/etc/hosts, install (anyway) haveged and rebooted.

We checked all that with Alex, but seeing nothing obvious.

So far, the web gui usage is still a real daily pain.

Hi,

Thanks for taking time and reverting back to me.

I have seen this explanation from engine-backup help and realise that it is
something to do with Postgres DB restore activity. But not much said about
it. I feel it instructs Postgress DB to restore the DB without privileges
with which the object was created, but use new permissions & privileges
passed along with --change-db-credentials and others passed during
engine-backup --mode=restore.

Exactly.

And if you do not pass --change-db-credentials, you'll simply get the
default, which is to just give permissions to the user creating the
schema.

Bottom line: If you used only defaults, and did not create users
and give them grants, there is no difference between the options.
They'll create the exact same database. If you did add grants, you
must choose.

I agree it's not very user-friendly to require choice, but please
take into consideration that if you had a large setup (say hundreds
of VMs or more) with dwh history included over some time, you'll have
a large database, and I think it will be much less friendly if we
"just try" restoring (which can take several hours then) and fail
in the end due to missing users.

Please also see the discussion on these bugs for more details:

https://bugzilla.redhat.com/show_bug.cgi?id=1217402

 It is highly likely 1 of 2 things:

 1. The entropy mentioned by Brett, however that is mostly
 applicable on hosted
 engine as VMs don't usually have good entropy.
 2. The engine cannot resolve itself (which looking at your
 description is the
 likely culprit). Since you don't have DNS, you need to add the fqdn to
 /etc/hosts so it can resolve itself.

 1. The entropy mentioned by Brett, however that is mostly

 applicable on hosted
 engine as VMs don't usually have good entropy.
 2. The engine cannot resolve itself (which looking at your
 description is the
 likely culprit). Since you don't have DNS, you need to add the fqdn to
 /etc/hosts so it can resolve itself.

[ovirt-users] Terribly slow web consile post migration of oVirt Engine from one host to another host

2016-06-08 Thread Anantha Raghava

Hi,

I was able to migrate the oVirt Engine from one host to another using 
engine-backup utility. On the new host, the data is loaded properly but 
the Administration Portal is terribly slow.


It take about 2 to 3 minutes to allow me to enter user name & password. 
Once logged in, it takes hell a lot of time to show up the data. Click 
on a tab, we need to wait for a good amount of time to see the actual 
data. Even the refresh is taking time to execute although it is set to 5 
Seconds.


But if I enable old server and connect, every thing works quickly.

Note:

1. We do not have DNS in our environment.
2. Engine name & even the IP is retained the same.
3. Before migration, we stopped ovirt-engine on old server, took the 
backup, shutdown & disconnected the old server.
4. We installed the ovirt-engine on new server, run engine setup, noted 
down the DB password, did engine-cleanup, restored the data using 
engine-backup utility and executed engine-setup again. It did recognize 
restored data and only httpd configuration was sought and we selected 
the defaults.


Result is terribly slow Web Console.

First, we attempted to setup ovirt-reports and later removed it thinking 
that may be slowing down the engine server. Yet the same result.


Commands used to backup from old server: "engine-backup --mode=backup 
--file= --log= --provision-db"
Command used to restore on new server: "engine-backup --mode=restore 
--file= --log= --change-db-credentials 
--db-host=localhost --db-user=engine --db-name=engine 
--db-password= --no-restore-permissions"


The command executed without any errors, resulting in a terribly slow 
web console.


Note: Without --restore-permissions, the restore fails. Did not 
understand what to give as restore permissions. Hence used 
--no-restore-permissions.


*Hardware configuration:*
*
**Old Server:* i3 Processor, 4 GB Memory, 1 Gbps NIC
*New Server :* Lenovo x3250 M5 Server with Intel Xeon Processor, 16 GB 
RAM, 2 X 1 Gbps NIC.


Just unable to understand why it is terribly slow.

Re: [ovirt-users] oVirt Windows Guest Tools & Live Migration issues.

2016-06-08 Thread Anantha Raghava

Hello Michal,

The Live Migration fails. Events does not show any information but just 
mentioning migration failed. This happens even when we put the host into 
maintenance. VMs do not migrate and host fails to move into maintenance 
mode.


Attempted to upgrade the Hosts, but failed, no reasons attached.

I am a bit lost at this stage. Should we check for some more information 
in some logs? If yes, where do we find the logs?

Hi Anantha,
it’s part of ovirt-guest-tools. See

Live migration failure - These are pretty busy VMs if not big. The 
event does not show any specific message but just as migration 
failed. Is the reason logged somewhere? Please share the log 
location so that I can check & share the log for meaningful message 
and proper screen shots.


There should be more details in the events at the bottom of the 
webadmin page (just make it a bit bigger it may not be te last message)
If they are busy VMs then you may have issues migrating them. There 
is some simple tuning available and it may help. You can increase the 
maximum downtime in VM properties dialog (500ms by default, you can 
go up to whatever is feasible for your VM, seconds, tens of seconds)
Bandwidth is limited to work on 1Gb network, if you have 10Gb 
availabl you can also tune /etc/vdsm.conf on each host and increase 
the maximum bandwidth 10 times

Hi,

I have a peculiar problem with oVirt 3.6. Any VM connected to ovrtmgmt 
is working absolutely fine, bu the VMs (Windows Guests) in different 
VLANs say 10, 32, 34, 40, 48 & 69 are not able to even ping their 
respective gateways. In other words, network packets are not coming out 
of the VMs at all.


1. Our infrastructure consists of Lenovo Flex Chassis with 3 Lenovo x240 
Compute nodes. All nodes are up and running and VMs are also created and 
guest OS installed.

2. Chassis switch has a trunk port that carries all VLAN traffic.
3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 
48 & 69).
4. I have attached the vNIC to each host and assigned static IP in 
respective VLANs. For example in VLAN 32, the vNIC is assigned with 
172.20.101.70, subnet: 255.255.255.192, Gateway: 172.20.101.65
5. VMs are mapped with respective vNIC and assigned IPs in respective 
VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as IP, 
255.255.255.192 as subnet and 172.20.101.65 as gateway.


Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to ping 
the gateway nor hosts are able to ping vNIC or the VM.


We even attempted with replacing a trunk port with access port, but same 
issue continues.


What could have gone wrong? Any thing missing on oVirt configuration?

A quick help is highly appreciated.
