    DRBD recovery issue...

    Hello everyone, I hope this is an easy fix. I just recently upgraded from Promox VE 1.9 to 2.2 I've also switched from a single box to a cluster configuration. When i say "upgraded" that means "back up all vms and install fresh & restore vms" The cluster shares disks via shared LVM+DRBD...

    ProLiant Microserver & 1 vm - pfsense= high cpu usage?

    Hello, I recently installed Proxmox VE 2.0 on a proliant microserver in stock configuration (2G ecc ram, 250G sata disk). I've installed a single pfsense (2.0.1-RELEASE) vm and have given it two virtual nics. The nics are actually 802.1q virtual interfaces on the host. DMZ is vlan 10, lan is...

    balance-alb on host causing problems with guests.

    It looks like there is a known bug with bridge & bonding! See the bottom of this page: http://www.linux-kvm.org/page/HOWTO_BONDING This might be good to put into the wiki... Edit:Especially see comment #13 here: https://bugzilla.redhat.com/show_bug.cgi?id=584872

    balance-alb on host causing problems with guests.

    To buy a switch that supports this here is about $600'ish for the 48 ports that I'd like to have (wiring the whole house)....way out of my budget at the moment.

    balance-alb on host causing problems with guests.

    I have each of my 3 vm cluster nodes setup with balance-alb across two nics. My "gateway"/firewall (openbsd) is a guest that is bridged to one of the bonds. eth0 + eth1 = bond0, bridge to vmbr0 However when I try to ping the guest, I get a lot of icmp redirects. Sometimes I'll get 2/3/5 in a...

    Strange networking behavior (e100)

    Hello everyone, I recently setup my 3rd host node and have bonded (alb) pro/100 interfaces to bridge to the wan vlan, an e1000 for the "lan" bridge, and an r8168 on the "pfsync" vlan. After setting up bonding on the e100, if I ping the (public) ip of the GUEST from my firewall/gateway, the MAC...

    live migration didn´t work on AMD?

    I'm having a similar issue. Both 2.6.32 boxes. Migrating from an amd 5050e to an athlon ii x4 620. on iscsi/lvm. This is as far as it gets: /usr/sbin/qmigrate --online 192.168.75.86 102 Apr 06 17:20:41 starting migration of VM 102 to host '192.168.75.86' Apr 06 17:20:41 copying...

    Iscsi performance problem.

    Hello everyone! I recently setup freenas with NFS & Iscsi. For the nfs part I have 10 * 500G in a raid10. Performance is pretty good. For the iscsi setup I have 4 * 60G OCZ agility (brand new, latest firmware) on an ibm serveraid controller. I'm using them individually right now. The...

    vm migration hang

    Thanks. qm list showed me the vm's. qm stop 101 gave me: "trying to acquire lock...got timeout" I did get the pid though and a "kill -QUIT <pid>" fixed it. Thanks, Robert

    vm migration hang

    When testing iscsi, I tried to migrate a vm & it hung. This is a test vm with nothing important (I shut it down & made a backup before restarting it & trying the migration). How do I kill this? If I tell it to cancel in the webgui nothing happens. Is there a CLI command I can use to...

    L3 cache importance

    Very interesting. I am pretty sure my 5050e/4850e/2350 are all around 100W under load ea. Also: What coolNQuiet steppings do the 965/955 support?

    L3 cache importance

    the 620/965 dont' have much price difference, but I'm really interested in the 45W quad cores. I have 4 boxes, and the "server room" is in a basement with the furnace that heats the house. With 3 45W cpu's right now it is around 70-80F (21-28C I think). I'd really like to keep the power...

    KSM - CPU Usage 20 - 50%

    I agree. I ran into this situation as well after almost 20 days of uptime. I turned off KSM.

    How does proxmox handle VE IOWAIT?

    Use shared storage/NFS that is hosted on a ZFS server with SSD cache (FreeBSD 8 should support this). Rob

    L3 cache importance

    I'm using only KVM (as I use more than just linux) with the new kernel with KSM. My proxmox cluster will be made up of multiple SSD's (Intel/OCZ) over nfs with bonded gigabit ethernet. Backups will happen nightly to a repo of My vm's (to start with) will consist of 3 internal...

    L3 cache importance

    I'd like to see how say, the 965 reacts vs the 620 when trying to run, say 16-32 vms' on 8G ram. Is the 965 able to do it at a decent speed where the 620 is not? How is the performance of the vm's under some load?

    L3 cache importance

    Hello, I am going to be running a 4 server cluster with shared NFS filesystem (possibly on one node, possibly on a 5th node...). I have some quite old cpu's, except for one I traded for: Currently only "new" cpu: athlon ii x4 620 Old: be-2350, amd 4850e, amd 5050e. Proposed new...

    Proxmox 1.5 2.6.31-1-pve kernel missing nfs support?

    I tried to install/run nfs-kernel-server but when starting the server, it tells me the kernel doesn't have nfs support. Is this an oversight or on purpose? Does it break something if I use one of the kvm hosts (no openvz here) as an nfs server as well? Edit: I'm using 2.6.32-1-pve not...

    New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32) [UPDATE]

    Re: New Proxmox VE Kernels (2.6.18 - 2.6.24 - 2.6.32) I have had similar problems with r8168B + r8169 module. The trick was to download/build the r8168 driver from realtek, install it and blacklist the r8169 module. After you do this, do an update-initramfs -u -k `uname -r` and that should...
