similar to: Virsh blkstat doesn't work on Xen HVM

Just to clarify my problems: For each KVM virtual machine, it is actually a process running on the host. The $pid in "/proc/$pid/io" represents the VM process’s PID. All my work is done on the host, not inside the VMs. Take the VM process’s pid is “pid”, What the /proc/$pid/io records is io statistics of the VM from the host’s perspective. I understand that qemu might do some I/O

Hey folks. Currently, I am working on an accounting-solution for Private Cloud with Eucalyptus as my bachelor-thesis. Eucalyptus bases on libvirt providing the KVM machines. Part of the thesis is kind of measurement for the uptimes of each instance in the cloud. As Eucalyptus is based on libvirt, i want to know if there is kind of tool already setup for monitoring a vm in terms of uptimes,

Hello Everyone! I'm Ameya Sinha, a student, and I wanted to contribute to the libvirt organization. I have read through the contributing guidelines ( https://libvirt.org/contribute.html) and contributor guidelines ( https://libvirt.org/hacking.html). Can someone suggest how should I proceed from here? Thank You, Ameya Sinha

Hi, all. While monitoring KVM VMs’ disk utilisation using libvirt API “virDomainBlockStats", I find that the results acquired is not consistent with the value read from /proc/[vm_pid]/io(i only care about “rd_bytes" and “wr_bytes” fields). Since libvirt doesn’t support host level monitoring, i have to calculate the host’s disk utilisation by reading from the /proc/diskstats file.

Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.

Hi, I'm having problems with libvirt crashing after a couple hours when a specific domain monitoring program is running. I have pasted below the following: 1. libvirt version 2. qemu-kvm version 3. OS version 4. Kernel version 5. libvirt status post-crash 6. libvirtd.log (info level dump around crash; too long to post everything so just the beginning and end. UTC) 7. custom.log (on what

Hi and hello, I have a problem confusing me. I hope someone can help me with it. I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines. Commands (for completion): [i]zfs create rpool/vms[/i] [i]zfs create rpool/vms/vm1[/i] [i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i] This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the

As I mentioned, I got the instances to launch... but they're only taking HugePages from "Node 0", when I believe my setup should pull from both nodes.

Use PM_FREEZE, PM_THAW and PM_RESTORE power events for suspend/resume/checkpoint functionality, instead of PM_SUSPEND and PM_RESUME. Use of these pm events fixes the Xen Guest hangup when taking checkpoints. When a suspend event is cancelled (while taking checkpoints once/continuously), we use PM_THAW instead of PM_RESUME. PM_RESTORE is used when suspend is not cancelled. See

*facepalm* Now that I'm re-reading the documentation it's obvious that <page/> and @nodeset are for the guest, "This tells the hypervisor that the guest should have its memory allocated using hugepages instead of the normal native page size." Pretty clear there. Thank you SO much for the guidance, I'll return to my tweaking. I'll report back here with my results.

Hi list! I follow the Samba 4 HOWTO on Ubuntu 10.04, git ok make ok make install ok make ok (needed for provision to work, even though i use the installed provision) /usr/local/samba/sbin/provision --realm=samdom.example.com --domain=SAMDOM --adminpass=SOMEPASSWORD --server-role='domain controller' ok added "domain samdom.example.com" to resolv.conf When starting Bind 9.9.0b1

destroy() is being called on exception in both start() and create(). It needs to be called only in create().

Any idea what happened to cause it to partially fail and get into this state? virsh blockcommit --pivot is actually 3 operations in sequence: 1) initiate the commit job 2) wait till it finishes 3) initiate the pivot job (this is

We used to stop the handling of tx when the number of pending DMAs exceeds VHOST_MAX_PEND. This is used to reduce the memory occupation of both host and guest. But it was too aggressive in some cases, since any delay or blocking of a single packet may delay or block the guest transmission. Consider the following setup: +-----+ +-----+ | VM1 | | VM2 | +--+--+
