I've been running into a reproducible problem when using default LVM volume group names to present block devices for virtual machines in KVM, and I'm wondering why it is happening. On dom0 I make a default VolGroup00 for the operating system. I make a second VolGroup01 for logical volumes that will be block devices for virtual systems. In VolGroup01, I make two lv's for one system: lv.sys1, and lv.sys1-data. I then build a new virtual machine called sys1, using lv.sys1 for the root filesystem, and lv.sys1-data for an independent data partition. Everything...

By removing all references to VolGroup1 in /etc/fstab I was able to get a system that boots. Unfortunately I am not that familiar with LVM but using the following commands it looks like all the information about my logical volumes on VolGroup01 is gone is this correct? Is t...

Hi A few days ago we rebooted a server and found that one of the Logical Volumes would not mount at boot, but mounted cleanly manually. So I traced the problem to SE Linux. Specifically the context for /dev/mapper/VolGroup01-lv_ staff is wrong. s -lsahZ /dev/mapper/VolGroup01-* lrwxrwxrwx. root root system_u:object_r:quota_db_t:s0 /dev/mapper/VolGroup01-lv_staff -> ../dm-25 lrwxrwxrwx. root root system_u:object_r:device_t:s0 /dev/mapper/VolGroup01-lv_student -> ../dm-24 I have tried to correct this with the Log...

Hi. I am new to CentOS (Debian user) and I am looking for way how to install CentOS 5 on domU in the way that I have it directly on dom0 LVM partition. If I install it with virtual-manager then the installation program takes that partition as a disk and then creates new partitions on it. I don''t want it that way because I cannot then mount it from dom0. Is there some way how to

...essfully but when I boot the kernel with xen  it will restart the system  after loading some xen modules without giving any error message. what could be the problem. Also i found some issue with manual grub entry at the end of the whole process. where we specify the boot partition root=/dev/mapper/VolGroup01/vg_fedora11 ro I don''t find the vg_fedora11 on the given path.

Hi all, How can I boot a XEN domU guest into safe mode? One of our servers was forcefully shutdown, and it seems like one of my VM''s could be corrupt, or something.

I have some problems with copying LV volumes and determining correct size. For instance, if I want to copy an LV from one machine to another. I dd the LV to a file on the other machine, then dd the file to the new LV. That fails, because a few MB are missing. source: LV Name /dev/VolGroup01/LogVol01 LV Size 4.62 GB target: LV Name /dev/xenvm/lvmtest1 LV Size 4.62 GB Both were created with lvcreate -L 4.62GB, but there's obviously a small rounding or whatever difference. The size of the physical extents seems to be different....

Hi All, I have working CentOS xen guest (domU) inside in Debian xen domain (dom0) and here is the domU''s config file <http://fpaste.org/paste/7295>. How could I put the proper syntax inside of domU''s config to instruct the domU to boot the /data/CentOS-5.1-i386-bin-DVD.iso during starting of domU? BTW, I am using xen-3.2-1. Thanks, James

Hi: Reading Red Hat''s Website and a printed manual of RH184 (Red Hat Virtualization course) I see that RHEL 5 only supports RHEL 4.5 and RHEL 5 as paravirtualized guests. So I asume this is the same situation for CentOS 5, right? What''s the dependency between Xen versions for paravirtualized guests? I ask this questions because I got this experiences: 1.
