Re: [CentOS-virt] How do I do Centos 7 p2v migration?

[Gilberto Nunes]

Do you get it??

 Hi

 I do this last week, and I use CloneZilla to generate a file image from a
 phisical server running Ubuntu and after that, used Clonezilla to restore
 into KVM hypervisor with no tears...

 Very smoothly...

 Cheers

 Hi,

 I am trying to figure out how to do p2v and v2v migrations on a Centos 7
 kvm
 host. With previous versions there was virt-p2v but that does not seem to
 exist
 with Centos-7.

 I realize that if I am using shared storage, I can do live migrations but
 that does not help with p2v migrations.

 Does anyone know what the recommended procedure is for migrating either
 physical or virtual machines to Centos-7 is?

 I have tried searching for the answer but my google foo is not being
 helpful.

 Regards,

[CentOS-virt] KVM and shared disc...

[Gilberto Nunes]

Hi all

I have deploy some VM's with MS Windows 2008 R2.
I deploy it using virt-manager, on CentOS 6.
On the same host where I installed CentOS I have installed LIO-Target to, in
order to providing iSCSI storage to VM's, 'cause I need install Windows
Cluster failover here.
I was work with iSCSI initiator from inside each VM's but this pratice show
me very instable situations.
Now, I use iscsi-initiator direct from host, on physical linux server and I
try to seek the iSCSI storage from that host...
I was capable  to found the device and attached into VM settings, via
virt-manager.
But, when I try to start the VM, I get this message:

libvirtError: internal error Process exited while reading console log output
char device redirected to /dev/pts/2
qemu-kvm+ -device lsi,id=scsi0,bus=pci.0,addr=0x7: Parameter 'driver'
expects a driver name
Try with argument '?' for a list

Someone has take this error someday???

Thanks

 Hi all,

  I need to install a virtual machine acting as a virtual storage server under
 CentOS 5.x (using kvm, xen, virtualbox or vmware). This virtual storage 
 machine
 needs to server storage to another ESXi server and at the same time to the 
 host
 where is installed.

  This is due to the limitations of hardware I have available. Both hosts 
 needs to
 server several machines.

  It is very important that the virtual machine consumes the least resources
 possible (host has 5GB RAM and i need to run three virtual machines minimum,
 including this storage server as a virtual machine).

  What can be better solution: CentOS, NexentaStor, openfiler ...??

  Many thaks.

[CentOS-virt] which virtualization platform to choose

[Gilberto Nunes]

Friends
I'm in doubt here: which virtualization platform to choose and why?

If I have just installed a VM I choose Xen or KVM?
And when I have more than 5 or 10 VM's?

Please, I need your help to choose right.

Thanks

Re: [CentOS-virt] which virtualization platform to choose

[Gilberto Nunes]

Hi...

How manu guest do you running??

thanks

2010/7/26 compdoc comp...@hotrodpc.com:
 KVM seems to have a future in centos.

 I have a couple of servers running kvm, with only 4 cores per server. I tend
 use 1 real core for each virtual cpu assigned to the guests, because I don't
 need that many guests. So, I can't speak to scaling...

 Performance is excellent, however. It's been a year or more since I've tried
 ESXi or xen on ubuntu, but I was always disappointed in the speed at which
 the guests ran.

 That's why I turned to xenserver for its speed and GUI, and then to KVM for
 its speed and complete control over things like nics and network
 configurations.

 KVM works great

 It depends on many things.

 If your hardware doesn't have CPU virtualization extensions,
 then you only have one choice - Xen.

Yes. All hardware has virt extensions...

 If you want to use 32bit host OS, then you only have one choice - Xen.

Yes... All software is 32 bits
 And if you run mainly Linux VMs then Xen is a good choice.

No... Mostly software is Windows based here...

 Tks

 Did you upgrade and then downgrade on the same machine it's not working 
 properly on or are they different physical machines?

 Did you verify that Xen has those 4 CPUs assigned to the guest? Did you 
 install Windows with SMP support or add SMP support after you added more CPUs?
