Hi All,
I'm trying to have my Linux KVM (a CentOS 6.4 VM with no GUI) access my hypervisor's soundcard. I'm reading succesful attempts for Windows clients, but they don't work for my Linux client.
I've tried adding the following to my .conv file:
Code:
args: -device AC97,addr=0x18
and
Code:
args: -device intel-hda,id=sound5,bus=pci.0,addr=0x18 -device hda-micro,id=sound5-codec0,bus=sound5.0,cad=0 -device hda-duplex,id=sound5-codec1,bus=sound5.0,cad=1
Both give my client a soundcard, but playing on that card doens't produce any sound. :(
My setup is as follows:
I've connected an USB soundcard (very basic) to the hardware and on the Proxmox hypervisor, and I can access it through ALSA:
Code:
root@pmx1:~# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

This plays music.
On the client, when using the AC97 variant I get:

Now, aplay reports no error message, and apparantly plays the music, but nothing comes out my speakers :(..
amixer reports volumes are at 100%.
Same thing when trying the other args setting.
Any help?

Recently I have a problem with a virtual machine in which is running an ecommerce. The paypal module is not working anymore so I have to test the connectivity with this command:
curl -d "test" https://api-3t.paypal.com/nvp -v
I get
* About to connect() to api-3t.paypal.com port 443 (#0)
* Trying 173.0.84.69... connected
* successfully set certificate verify locations:
* CAfile: none
CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* SSLv3, TLS handshake, Server hello (2):
* SSLv3, TLS handshake, CERT (11):

* SSL certificate problem, verify that the CA cert is OK. Details:

* Closing connection #0
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
If I test from the main proxmox machine the command work fine, If I move the vm to another server the command work fine.
I can't understand If is a problem regarding proxmox.

Hi,
I have made some rados benchmark and I'm see high max latency (rados -p test bench -b 4194304 60 write -t 32 --no-cleanup).
does anybody know how to find and isolate the reason for the high latency?
Code:
Total time run: 61.186561 60.008194
Total writes made: 7045 100939
Write size: 4194304 4096
Bandwidth (MB/sec): 460.559 6.571
Stddev Bandwidth: 98.5743 5.50003
Max bandwidth (MB/sec): 568 15.4883
Min bandwidth (MB/sec): 0 0
Average Latency: 0.277103 0.0190213
Stddev Latency: 0.227484 0.120132
Max latency: 4.81041 4.09047
Min latency: 0.067239 0.001231
One thing I found is the numbers of threads - the throughput is better with more threads - even on a host with only 8 cores the performance is with -t 32 much better as with -t 8. But the max latency also rised up (but only slightly).

Hi there,
i have a openmediavault installation as a vm in proxmox. The HDDs are added like that in the vm.conf:
virtio1: /dev/sdc,backup=no
virtio2: /dev/sdd,backup=no
virtio3: /dev/sdf,backup=no
virtio4: /dev/sde,backup=no
virtio5: /dev/sdh,backup=no
virtio6: /dev/sdi,backup=no
The data transfer speed is quite fast (around 110 MB/s) but i have no chance to get the energy saving or SMART functions working in omv, cause it only shows the HDDs without the real information of the HDD.
Can i use Proxmox itself to get my HDD into energy saving mode or is there no access from proxmox to these HDD (cause they are attached to the vm)?
Some months ago i had attached the HDD via scsi and as i remember i could use the power saving and SMART function in omv (if i remember correctly the speed was around 50 MB/s). But now i dont really change my configuration by try and error, so i ask the following question in advance:
What is the best solution (speed and functionality) to pass through the HDDs to my omv vm?
Thanks in advance!

I cannot edit either options or resources for a container in 3.1.
Is this because I have two nodes in a cluster? Or because I have them stored on NFS?
Or did I just break it somehow? I see that permissions are owner root and group is the web server. I thought I should give www-data write perms on the /mnt/pve but it errors with function not implemented, which I assume is because of the cluster.

Hi all,
I am looking for a few options/recommendations for the following scenario in case I have missed any options myself. I am moving about 5 hours away from where I am now. It would be really nice for me to get my proxmox VMs migrated to the new location with minimal downtime. Can anyone suggest the options for me to do this. The easy way is to just let eveyone know that the server will be down for 6-7hrs however since I have to do this move during the day on a weekday that is my least favourite option. The following are a few details about the scenario I'm facing.
* I'll need to migrate about 225GB worth of VMs
* I already have hardware running at the remote location
* 3Mbps upstream at my current location (225GB will fit within my monthly transfer limit so no extra charges there)
* Will be migrating two windows servers (one exchange server and one application server)
Thanks for any suggestions

Hi,
I have few nodes with eth0 as main IP with Internet IP and eth1 with Internal IP (192.168.xxx.xxx)
on each node we have few OpenVZ VMs
and we have another Backup device that work with eth for internal network and eth for Internet IP
we wont to do the OpenVZ VMs backups via the internal network.
now, even the eth1 is configured, any connection include 192.168.xxx.xxx Goes through eth0 (Internet IP)
I'd be happy to help detailed how to make to
192.168.xxx.xxx go into eth1

There is a docu
http://pve.proxmox.com/wiki/SPICE,
but is seems there is no special information for debian - VM driver.
Debain 7 says that the monitor is unknwon.
I installed according
http://www.spice-space.org/page/Repositories
xf86-video-qxl

using the debain repos.
Now I can select a higher resoltion than 1024 x 768. But the monitor is still unkown.
Some hints to get an optimal configurated system?

Hi, There is typo in PVE31 /etc/cron.daily/pve file that prevents dir /var/log/pve/tasks/D celanups. Fix: - foreach my $subdir (qw(0 1 2 3 4 5 6 7 8 9 A B C F E F)) { + foreach my $subdir (qw(0 1 2 3 4 5 6 7 8 9 A B C D E F)) { Question: for security reasons we would like to stop external update services autoquerying from our hypervisors. Is it enough/safe to comment out lines 32-52 in /etc/cron.daily/pve? If so - please consider splitting updates/cleaning functions into two separate files in /etc/cron.daily - will be easier to disable update task without code modifications. Thank you for great software! Regards, Pawel IB Development Team

Hi everyone,
I am relatively new to this field and want to install a new Proxmox. I must say it is great. I have already installed Proxmox and two virtual Machines. The Hypervizor is inside a company networt. It will have a few machines on it(tree virtual servers and a virtuell client pc, all of them running with Windows). The Servers schould communicate to each other, but stay unseen to my company Network. For this purpose I created vmbr1 from the Web Interface and gave it an internal IP like 172.10.10.1 this. Then I would like to give my Virtual Machines an internal IP like 172.10.10.99 and Default Gateway 172.10.10.1, same as vmbr1. I am not exactly sure how to make this. This is what /etc/network/Interfaces looks like this:
Code:
# network interface settings
auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
auto vmbr0
iface vmbr0 inet static
address XX.XX.XX.xx #external IP
netmask 255.255.0.0
gateway XX.XX.XX.XX
bridge_ports eth0
bridge_stp off
bridge_fd 0
auto vmbr1
iface vmbr1 inet static
address 172.25.25.1
netmask 255.255.0.0
bridge_ports none
bridge_stp off
bridge_fd 0
How could I connect my VMs to vmbr1 instead of vmr0? How could I connect vmbr1 to vmbr0 in order to communicate in the internal Network. I will try to make same basci Diagram in order be clear what I mean. Thanks in advance!

-rw------- 1 root root 48621568 Nov 18 11:46 umzug.iso
in gui, i work as 'root@pam', so it should be no access-problem.
i can see all virtual server. i can stop and start these server. but i can't see any backup-file of these server on the backup-storage with the gui.
i found no errors in the logs. PVE-Version is 3.0.23

Hi Everybody,
I just set up a proxmox VE on a EX40-SSD at Hetzner and I am experiencing funny network behaviour... Generally said it's just not working so well. I already installed other systems on exactly that server and they are working fine, it's just getting fucked up when I use proxmox.

Needless to mention, normally that's blazin fast!
I noticed that during the installation the Realtek firmware gets replaced with some other kind, I guess it has to do with that?
Did anybody else have the same problem? Hetzner doesn't support the proxmox image...

Can someone explain to me what happens "technically" when Proxmox takes snapshot backup of a running virtual KVM machine on a LVM storage?
The reason why I ask is that I always use the "backup stop option" on windows servers to keep a consitance backup image.
Can you be sure that images of servers with running databases a keep in a consitance state when "backup snapshot option" is used.

Hi,
We have a planned to setup a failover cluster for PostgreSQL db which initial plan was setting up using RedHat Cluster Suite. But since I just got to know Proxmox virtualization, anyone here can suggest me if the Proxmox virtualization can support same efactures as failover clustering using Redhat Clsuter Suite.
Our typical setup will be two physical server with Iscsci Storage, but if we plan for virtualization ( If proxmox support failover cluster ), we will convert this two physical server to virtual environmnet to allow more VM's to be install.

hello
we chanched from KVM/virsh to proxmox. However as there is no option for using existing images (that is really missing) we just created new machines- then made an lvmremove of the newly created lvm and then an lvrename from the old lvm to the new name of proxmox...
this works but now i dont see any of the lvms when i look on the content of the volume group.
but lvmscan show me all volumnes normally...
why does proxmox dont show any?
and maybe os there a better way of migrating the lvms? i just installed the proxmox on the host without deleting the lvms of the guests (first installing debian and then proxmox...)
thank you
